Which content creators do you guys watch for genuine gameplay tips/improvement?

I'm mainly looking for someone who's good at giving consise and clear advice, preferably while spectating. Admittedly I'm a bit picky - most of the ones I've found are either obnoxious/more focused on dunking on bad players than actually giving advice you can work with, or they sit in practice range and just talk about what to do instead of demonstrating/showing an example.

So far I've mostly just been watching Flats because he actually gives useful feedback with timestamps even as he's dunking on people. Is there anyone else similar to this that's worth watching?
