Antec units are generally well regarded, few people have trouble with them. They rank high among standard lightweight psu's.
I personally regard the Enermax models as a cut above, however. They're beefy, well made, quiet and have the cables from hell(long an lots of them) While you may not ever use the extra power, it won't hurt, either, so if you feel comfortable spending the extra $20 or so, go for it.
I'm not thrilled with the FC models, however, the whole concept is gimmicky and doesn't seem to offer any real advantage....
Neither brand does much for case cooling because of the quiet thermo-controlled fans. They're not designed to cool your case, just to cool themselves.
