so you r saying that HLE is faster but less accurate but LLE is slower but more accurate?

Yeah that's pretty much what I was saying.
It's not a absolute fact tough, it's more of a consequence of how each of the two methods work.

With HLE it's impossible to have high accuracy. You'll always have an issues. If it isn't for high hardware demands for LLE devs would never bother with HLE.

That depends on what you call 'high accuracy'. I like to think Project64 is very accurate nowadays. It's not perfect, but it provides perfect emulation in a lot of games. And even tough LLE leads to a more assurable path to perfect accuracy, that doesn't mean you couldn't achieve perfect emulation with HLE. It's just very hard for modern platforms emulation, unlikely even.

If you ask me, I kinda prefer High Level Emulation for most consoles. It's an improvement to the entire concept of hardware emulation, it's better and more clever than LLE. It's just much harder to implement right.
