I like Fraunhofer Pro for CBR files, but I think it's a bit outdated when it comes to VBR. The only people resistant to VBR are those with 1st Gen mp3 players that don't support it (same goes for the people that hate V2 ID3 tags). But, if CBR is your thing, Fraunhofer Pro is the way to go I spose (at least equal to lame.)

FWIW, MusicMatch uses Fraunhofer (not sure if it's Pro) and as I mentioned, I ripped my entire collection 3 times w. it before moving to Lame. Fraunhofer does seem to boost the bass a bit and people like that (kinda like how radio stations boost the bass and compression the dynamic range to raise the average volume.)
