Stephen King dark tower?
No. Not western, no guns, no science, not really horror.

WoT is the whole “forgotten/suppressed magic, ‘the one’, forces of long imprisoned evil” kinda fantasy, along with a rise to power, world politics, massive battles, adventure, and - I guess - romance.
Has a lot of the tropes, but carves a great story and adventure.
I genuinely recommend it. I’ve read it 3 times, and I enjoy the TV series.

It’s a 15 book epic fantasy, with the last 3 books written by Brandon Sanderson according to (deceased, 2007) Robert Jordans notes.

It’s good.
It has it’s faults, Robert Jordans writing has it’s faults.
But it is good, a great story, a great adventure, a great over-arching story. And 15 books long, makes it great read to sink into and enjoy.
