Bah, I meant to send this here, not to just one person...
 
OK, in order to talk about pros vs. cons, we need to consider the uses first. Some main tasks are:
1) selected an unvandalized version (for AT, this will do "worse part" checks and such)
2) selecting a quality, fact-checked version (German Wikipedia wants this)
3) selecting a consensus version/marking featured pages
4) selecting the best version and displaying it be *default*
 
Selecting an unvandalized version
Flagged Revisions (pros):
1) Templates and images are part of the review process, so vandalism to them will not show for reviewed pages
2) Users with review rights get the gratification of setting the latest unvandalized/"sighted" version
3) New users can look forward to getting these rights in short order, after being considered trusted
4) Edits by reviewers can be autoreviewed if they are to a page where the stable and current are synced.
5) If 4 above is not possible, a diff of the changes to the stable are shown after edit to reviewers with a review form with the tags preselected. It shouldn't take long at all to glance over the changes and click "review".
 
Flagged Revisions (cons)
1) Initial review takes noticeable time for non-stub pages
2) Revisions can fall out of date if not maintained, so people clicking to see a stable version may get a really old one. This is integrated with the RC patrolling system and with the autoreviewing/quick diffs to help, but it is still a possibility.
 
Article Trust(pros)
1) No workload added, all automatic. This is very nice.
2) Fast and fluid since calculations for the sighted version are done on every edit without anyone having to do anything
3) Accounts for consensus, so no rouge reviewer can easily flag garbage. Still, a "trusted" user can go rouge and add garbage, even in several edits to bump the trust.
 
Article Trust(cons)
1) Template and image vandalism is still a problem
2) Bot and AWB edits flying through pages automatically make the trust of large chunks of text increase
3) No direct control over it by anyone -> incentive loss
 
Selecting a quality, fact-checked version
Flagged Revisions (pros):
1) Trusted users, who have some respect for consensus as well, can directly mark off solid revisions
 
Flagged Revisions (cons):
1) If the user goes rouge they can flag garbage. Not as bad as rouge admins, likely rare, but something to think about...
2) A roughish user may ignore consensus and reasonable fact disputes. This could result in a small user or cabal having a monopoly over the "best version". Good policy standards and respect should be enforced to avoid this.
 
Article Trust(pros):
1) Nearly all "white" pages have a good chance of being reasonable accurate
2) No work required
3) Harder to form cabals/monopolies over the "best version"
 
Article Trust(cons):
1) Again, bots and such
2) You cannot edit anything without vouching for it (bad for fixing typos) and the text around it. Either people get afraid to edit or dubious text gets more and more "trusted"
3) No one necessarily committed to having fact-checked anything
 
Selecting a consensus version/Marking feature pages
Flagged Revisions (pros):
1) Trusted reviewers (higher flagging rights than normal reviewers), like bureaucrats, look at debates and see if a consensus for a community selected version exists
2) As long as the trusted reviewer acts like most "bureaucrats" on Wikipedia and just measure consensus, it is not easy to game
 
Flagged Revisions (cons):
1) Rouge trusted reviewer...blah...could end up at arbcom 
2) Not automatic...I mean look at how slow WP:FA stuff is...
 
Article Trust(pros):
1) It would take a lot of users to try to edit war to push the "consensus version" around since it is automatic, and that would just make a bunch of red text to the current revision which would cause it not to be selected.
2) Automatic, account for all edits, not just those "voting" on some talk page
3) Generally waaay faster
 
Article Trust(cons):
1) If there is consesus for a version clearly demontrated on a talk page, a small group of editors can still edit war over it and drop the trust. It would be nice for some trusted reviewer to be able to see this and expediently flag it.
 
Selecting the best version and displaying it be *default*
Flagged Revisions (pros):
1) Again, template/image vandalism won't be such a problem since those are set for each reviewed revision based on how it was when reviewed.
2) For bios of living people, we can easily and immediatly set the stable version without having to fiddle around getting it autotrusted.
3) The incentive issue again, reviewer can set this, and editors can look forward to becoming reviewers.
 
Flagged Revisions (cons):
1) Rouge trusted reviewer...blah...could end up at arbcom 
2) Spelling/grammar errors can get stuck if no one is around to review corrections (though reviewers spelling fixes could be autoreviewed sometimes)
 
Article Trust(pros):
1) The default is BY FAR the most important revision, so giving direct control over gives incentives to form evil cabals :)
2) As this is important, it helps to stay up to date with the workload, this requires none...so that's pretty easy... 
 
Article Trust(cons):
1) Spelling/grammar errors can get stuck since it's hard to directly control
2) The "highest least trusted" and "max age" and other heurestics will be confusing to new users. Default page selection will feel kind of random

This is still an imcomplete list probably...I should probably save this somewhere and build on it. Also, for default revisions selection on page view, I am just comparing the methods of selection by the two extensions. We could have it where Flagged Revisions does the overriding of the default revision, but that it grabs the Article Trust "most trusted" version rather than some reviewed one. This would just be to avoid duplicated code though.
