Advice On Sound Library Use

I need advice. I’ve never used Midi Guitar 2.
I’m working with a friend who professionally scores music on Logic with a MIDI keyboard to play acoustic and electric guitars. But he’s a great guitarist also and MIDI Guitar 2 might help him.

If he starts scoring music with MIDI Guitar, what sample libraries should he use with it?
He has MusicLab and Kontakt Session Guitars and Orange Tree and Guitar Rig for processing.

Are there amazing sample libraries that work well for both acoustic and electric guitar emulation using MIDI Guitar 2?

Any other thoughts or suggestions on professional scoring with sample library guitars in Logic using MIDI Guitar?

Cheers.
