In any case, coming from a 7700k hardly seems like an upgrade. You'll be losing a some performance in gaming and lightly threaded workloads. You'd have to really need those additional cores for it to be worthwhile.
The X370 are quite mature, but must make sure that you get one that has a sticker "2xxx compatible". I don't think the chipset itself has been a problem for a lot of people. Almost everyone had issues with RAM, which have been tremendously improved with BIOS updates and, if I understand correctly, resolved with the 2000 series.
I agree about the difference with the 7700K being minimal. Ryzen is probably more futureproof, even for games, but it only makes sense today if you plan on doing multithreaded stuff.
