The fallback caches can be quite useful for smaller wikis, although
since one still needs to be running in an environment where they have
more control than your average cheap hosting, it's possible that you
may prefer memcached. However, the eAccelerator and APC user caches
are fine for single application server environments, provided that
nobody else is running scripts on your machine.

I'll wager that most small-to-medium wikis benefit more from the
bytecode caching features of APC or eAccelerator than having a
slightly faster object cache available.
