Other posters will know I am not afraid to criticise BIAB and often do, but i want to jump in here and say that the Yamaha QY's though ok for their generation were far cheesier than BIAB (I have had all three types).
Real Tracks are live musicians and that makes a big difference. A (mouthorgan) harp for example cant be captured by MIDI or certiain feedback types of guitar.
Yes a lot of stuff is 'legacy', but this makes sense because it makes it useful to a wider market.
If you want to rehearse a set of chord changes for your band then there is enough here to get lift off. I often find that the way BIAB plays a phrase gives me inspiration and is very far from the original MIDI blat for on early Yamaha stuff (QY700)
Personally, my view is that there are lots of excellent tracks and I have learnt to enjoy genres that I have never explored - like country

BIAB widens ones ears

I say the best decision is to buy it

Just My opinion
