Booting with MAGLDR, I use different Kernel.
So what I think:
7.0 - Still have glitches.
BoxmaX+KS+v8.1.SD with Boot Magldr.rar is best of all. It fast and stable. Radio works pretty good. Animation is sensitive.
8.6 is to slowwww...
Also I found a little grafic bug in Gallery in all roms . Please fix it if no so hard.
