I’ve used the Boss GP-10, Roland GR-55 and VG-99. When I was playing on stage, I preferred the GP-10 due to its form factor, and the fact that I was really only needing bread and butter type guitar sounds. But definitely agree about editing programs on it.
If you can get your hands on a gently used VG-99, sound design becomes bliss with it’s large intuitive LCD and lots of hands on knobs and controllers to make adjustments with. Shame they discontinued it as I don’t think anything has been created since that really does what it does. It is really a bottomless playground for guitar.
The GR-55 is nice too. Kind of its own animal with the PCM synths.
I’ve definitely found hexaphonic (in particular the Roland solutions) preferable to pc/mac/ipad software.
