Not much to say about Virtua Fighter music as a whole...Some catchy stuff in the early goings (1 and 2), but it's been really generic and unmemorable material since then.
Never been a Tekken fan, but it's probably good stuff by techno standards. I've heard it off and on during gameplay and a piece or two here and there("Moonlit Wilderness" from the BSC), but I'd never sit down and listen to it seriously.
I still listen to a lot of fighting game soundtracks (everything Guilty Gear, the King of Fighters and Garou arranged albums, the Capcom VS series soundtracks, Battle Arena Toshinden 2), but the genre's just f---ing dead right now. I'd be glad to get a decent game, much less a decent soundtrack.
One cool recent one was the King of Fighters Maximum Impact 1 soundtrack. Really hardcore techno/rock stuff (It's hard to pin down what style that one was). Capcom Fighting Evolution is cool, but it was really short. Both were 2004-ish. And if you can stand the license, Dragonball Z3 had some great jazz/techno/rock material (Z1 and Z2 did as well, but they butchered the soundtrack release, so it's hard to recommend over the gamerips). And hopefully the Smash Brothers Brawl soundtrack will prove to be interesting with the all-star cast it has (probably will just be a gamerip).
And if you're counting brawlers (Final Fight-style games, ala the Bouncer, which you listed), there's both Shin Sangokumusou BB (my favorite soundtrack from last year) and God Tracks!
