I've been an OpenSuSE/Leap user for many years now and agree about the balance and stability. However there's still a pretty big gap between Leap and SLES (their enterprise distro) plus each Leap point release is only supported for 2 years (something like that).
Maybe it's better now, but there were a lot of packages available in Leap that weren't part of SLES. It's been a little while since I've last tried SLES - still super happy with Leap 15.2.
