To be honest all of these devices are extensively reviewed on Youtube.
Just google them and you'll have all the info you need.
Re anything with a Genesis or MD compatibility they all are, to a man, built around the same chipset and it is sh1te!
You get some games running fine but the music is wrong, playing too slow or glitchy.
You get plenty of games that don't work at all.
Better to invest in a Nomad tbh, at least everything will work.
Or just buy a Megadrive or Genesis and pick up the games you want, play them at home and if you want them on the go a DS or PSP is a good emu hosting platform, as mentioned by Retr0 there.
The Snes devices I know less about but the main complaints about these is always build quality, the controllers are not standard so not going to feel great.
The Hyperkin is not going to be playing PAL games, may not play Jap games and could have issues with certain games with exotic chipsets or instructions, like the Super FX games, I don't know, it certainly isn't a Nintendo product so is developed and released without their input.
The 3 in 1 is fun but it's just as easy to just own a Nes, Snes and Megadrive, unless you really want them all NTSC only, not sure if these things are region free, also the controllers are always going to be a compromise.
The Nes portable would be the only thing there to interest me, but again, whats the point?
It's not original hardware, the controllers are going to be different too.
Aside from using your own carts, which you can do on a proper Nes, you might as well save some space in your backpack and use a DS lite or PSP for your Nes dutied, given you could carry around the complete Nes backcatalogue without any region worries.
