What do I like? There are many things, but I won't cheat on this poll, so I bring it down to one point.
I Love:
The math works. It is transparent. No auto-hit or auto-failure. You can see how it works, at all levels.
I hate:
Hate is a strong word, but anyway - That the designers created a wonderful combat power system, but then decided to not try the same for non-combat powers.
Of course, I am certain of these things:
1) They would have come up with something very good, probably better then the equivalent stuff in Storyteller games or Torg.

2) That even more people would complain about the non-combat system. I don't know if it would have been called "Forgy", "Narrativisty", or "Storytellery", but I am sure most still in the "Rules as Physics" mindset would hate powers like
Well Connected or
Ancient Lore or
Escape Route.
Well, maybe 5E will have this. Or Unearthed Arcana 4E. Or d20 Modern 2.0...
