. The music would probably improve a great deal because MSX-MUSIC/MSX-AUDIO rocks and Adlib... kinda sucks 
But the AdLib has an OPL2... How can that suck compared to OPLL and MSX-AUDIO?

Correct. But combining MSX-AUDIO and MSX-MUSIC you've got stereo which makes a world of difference to me. Also no sampling channel. May all be a limitation of the tracker, not the card itself.
In fact, it may well be that theoretically capabilities are the same, or the PC soundcard of the era outperformed any MSX hardware. But in practice I think the MSX hardware was much better utilized. If I play an early game on the PC with Soundblaster support, I'm not blown away by the music (to say the least), while MSX games even with the very limited FM-PAC offered a much better experience. Just an opinion, of course
