The power tabs and guitar pro tabs are a big step up over the text based stuff on ug. You can play it in midi and see they are usually perfect.

Obviously I've had access to those for a long time. I would still say they are nowhere near as good as published material. And sometimes I've seen the community text ones actually be more correct.

Really a question of how much you pay for it. Sounds like some plans are $25/month, that's enough to just buy tons of published material instead. I paid $5 for a lifetime membership.. very worth it.

It sounds perfect which is part of it, but if you've ever looked at the Pro tabs, especially the vocal transcriptions, the fretboard positions are all over the place, seem to be wrong about half the time, and in the worst cases I've seen nearly physically impossible to play.

Also for unknown reasons (licensing?) it's impossible to have the vocal track play when you're using a backing track.
