I'm curious. What are your favorite level groups, and why do you like them? The sunny Aurora Isles with their Jelly Farms? Or the more ominous Candlestick Keeps? Vote for the one you like most! I'll keep a running tally which I'll keep updated. Maybe.
Boss stratums are separate because they're speshul. Vote for them separately.

.......Aurora Isles: 6.8
...Candlestick Keep: 3
..Clockwork Tunnels: 1

Personally, I'd go with Scarlet Fortress levels. I love the atmosphere of it; it really feels like an actual exploration rather than "kill everything that moves, and some things that don't". The layouts seem well thought out, and overall tend to be less linear than some other maps. Aurora Isles comes close (Jelly Farm!), but eventually I get tired of mowing lawns. :P
Gloaming Wildwoods for boss stratum, <3 Snarby.
Aurora Isles and Royal Palace.
Pink cubes, the most harmless enemies ever.
