PC P&C is well respected, I would also put a vote in for Enermax as a top-tier PSU (as well as often pricey!).
Antec and Enermax are more complicated, since they both have low-end lines that are, frankly, not that good (though still better than off-brand crap PSUs), and high-end lines that are competitive with the very best units out there. Antec TruePower/SmartPower/NeoPower PSUs are pretty good, but the generic ones are just meh. The Enermax "Liberty" line is very good, but some of the cheaper ones are not.
PCP&C probably has the best objective "quality", but you also pay through the nose for it, and their PSUs are not particularly quiet or efficient (but are built like tanks). For the money, I'd rather have a Seasonic (which is quiet and efficient and IMO of similar build quality).
Silent PC Review and Tom's Hardware Guide both have extensive PSU tests (SPCR does them more often, and better, but only tests 'quiet' PSUs).
