I've been using NetGear with OK results, although I have to admit
that we're not super critical about switches.

My primary suggest would be to not pay too much attention to
the subjective reviews you'll see here, including mine. Instead,
I'd suggest finding and understanding a switch benchmark program
that gives a more objective evaluation.
