This is a great question, but it's a tricky one to answer. Some of the best Joy-Con alternative Switch controllers in this guide are equipped with motion controls built-in, meaning you can use them the same way you would your Joy-Cons for games like Mario Kart and Nintendo Sports, but there's no guarantee that they'll perform as seamlessly as official Joy-Cons do, since the other options aren't made by Nintendo.
If you mostly play your Switch handheld or like basic adventure games, then I wouldn't worry too much about motion controls as these are mainly for multiplayer titles and active games like Just Dance.
