The package management is much faster in 11.0, like a night and day difference. Maybe even faster than apt-get in some cases.

I don't use YaST that much -- the command line tool 'zypper' is more my speed. libzypp (used by both YaST and zypper) was ungodly slow in 10.2, a bit better in 10.3, and is blazing fast in 11.0.
