There are 2 main companies that make these devices, GPD and JXD, both Chinese operating out of Hong Kong. Both have a long history of making emulation retro hybrids, very similar to what the switch is doing. The jxds7800b is a great machine for retro play, although a bit on the large size, it ain't pocket material. It runs most emulators very smoothly but can't really run the dolphin emulator, which for those that don't know is Gamecube/Wii games. It also isn't great for playing unreal 4 engine games on Android but everything else is game, basically it runs last gen games equivalent, competing against vita and matching MS360 isn't much of a problem for it. Having said all that you get free apps like showbox and mobdro to watch all your favourite movies and channel's, sky sports, sky movies all for free, like the switch you can take it on the go or use on the TV. Right now that's out of the way there are 2 better alternatives, the GPD XD and JXD singularity, both machines have superior CPU/GPU chips than jxds7800b, the singularity is certainly the best machine out of the 3 but for overall value GPD XD is the one to buy. The latter 2 i mentioned have no problem running unreal4 and the singularity runs the dolphin emulator. The answer to your question is, yep the jxds7800b is worth buying, especially if you find a cheap one, also it's a great companion to have with other hardware you have, it will still be 2nd fiddle to your switch but it's certainly retro heaven that you will never have on dedicated gaming hardware
