I'd hardly call Gerrit a lame horse, more like a horse with funny spots on it and an extra tail.
Also: what's this mythical "best tool?" I've not seen it suggested before.

There are alternative solutions, but none of them are viable without development work. Gerrit is viable right now, in its current state. Its downside is that its interface is slightly painful.
Every tool we use is going to have something we dislike about it interface-wise. Let's work with the OpenStack team and improve it.
