i have no experience w/ the truewatt stuff. but from what i've heard the only real advantage they have over the Enermax's is that they are quieter. but all you need to do is mod the Enermax by popping out the fans and splicing in some Panaflo's. i did it to mine and it's the single best noise reducing project i've done. so if you don't mind the noise get the Enermax, but if noise is a big issue for you than just mod an enermax or get the Antec.
