It’s (mostly) Colemak! I use it regularly on my work laptop and when I’m not gaming. It’s so much more comfortable on your fingers since it lets letters roll together and putting the most common letters on the home row. There’s also not as much learning involved because it keeps a lot of they keys on the same hand and keeps a lot of the most common shortcut keys (Q, Z, X, C, V) in the same spot.

It’s so comfortable and much more fluid. If you wish to learn, check out the transitional layouts called Tarmak. They change a few keys at a time to help you learn quickly while not losing that much efficiency.
