Roland, Fender, Mesa, Cornford are all good
"Johnson" is a brand name for guitar, but, if you're asking if Johnson is a name brand guitar as in "quality" guitar, then I would say no. Johnson is an inexpensive guitar somewhat suitable for beginners.
Its opinionated, Gibson is a higher priced guitar but if you are a shreder and much more you want a Jackson , ltd ,or if fixed up a fender gibsons not the best
