Choosing the right amp for your act can be intimidating for a new street performer, and still pretty confusing for an old one.
The amp that’s right for you will depend on your act (guitarist? singer?) your budget, how much weight you want to carry, how loud you want the amp to be and so on. Put simply, when busking, no matter what your act is, each amp has its own benefits and compromises. There is no single amplifier which will suit the needs of all performers.
