Lots of options out there.
I like MO49 primarily
or
401a for medium temp applications
401b for low temp applications

Why not 134A it's apparently using a txv most of the problems I have with 134A come from cap tube systems and waxing I have the same issues with all refrigerants using poe oil and cap tubes.

I would say 401a but to each his own. I'm not a fan of hot snot or 134a. I've had issues w/ cap tubes & TEVs on anything running w poe including rtus .. We all know what the high temps do.
