Have you figured how you'd like to use it? Whether you are going bromide the aux line in or as an amp? I found the Roland Cube to sound good via it aux line in, Yamaha THR good as an amp, NUX mighty 8 good as an amp, blacstar fly works equally well as both, Vox was good as an amp... It really depends on your ears preference bro. I like portable amps for their mobility...
Things I'd look for, eq options, built in effects, aux line in, battery life(for mobile use), the different types of modeled amp options.
Hope this helps man.
I am now back to simple solid state amps but they have no mobility functions...
Best wishes...
