Understand where you're coming from - I've played OOO + Fcom from day one, so I wanted a more vanilla experience (actually less shiny stuff).
I haven't found a better one. But I am using MMM + http://www.tesnexus.com/downloads/file.php?id=2272 + NPC Static Levels and so far I'm very happy with it. I'm only playing with SI however and I'm only 56 hours in (lvl 6, very slow leveling stats) so I'm not sure how it will turn out - only MMM is touching SI, and I haven't been there yet.
This is interesting:http://www.tesnexus.com/downloads/file.php?id=31383, there's this too: http://www.tesnexus.com/downloads/file.php?id=32192 - but I didn't like aspects of them, so I pulled some stats out and made my own esp.
I would love to see a complete static overhaul mod though - stats, levels and loot are all that need to be done - no extra stuff.
