Sorry, I guess I didn't read the whole question.
HH Ultralight a-sym- This is the only hammock I've ever tried.
Nunatak Arc Alipnist- I like using a quilt rather than a bag in or out of a hammock. Much easier to get into, is lighter, and packs smaller.
JRB Nest- I find the underquilt much more comfortable then a pad because I found it a pain to get it under me while entering, won't move out from under you during the night, breaths much better, greater temp range due to the adjustments you can make, and packs smaller.
MacCat Deluxe- The tarp that came with the HH was to small for me.
Hope this is more of what you were looking for.
