Is it stronger than this?

Are handheld PCs worth it?
I always found the Switch too bulky to use but pic-rel is the same form as the Vita which I consider to be the perfect size for handheld consoles.
But to those who have any of them: Are they worth it? Do you play on the go or just in comfy locations at home? Would buying peripherals for your phone be better?

Are handheld emulator machines worth it? This one is supposedly powerful enough to emulate up to PS2 and GCN games but has something like this been a gamechanger for anybody who purchased one?
