Seems that "Best" is rather subjective and subject to your personal preference (comfort, weight, ease of setup, etc).
UL...perhaps better to chose the hammock based on comfort first (if you can't sleep decently in it to begin with, what's the point of having the lightest). Most hammock setups can be modified to some degree (changing out the suspension, using hiking poles for bridge hammocks, smaller or lighter tarps). Even the JRB BMBH that Ken sniffed at can be modified substantially if the desire is there (change to dynaglide/whoopie suspension, use hiking poles for spreader bars, remove bug net or cut it back to a partial net, remove the pad pocket from the bottom).
I could sleep on the ground on a 1/4" CCF mat under a cuben poncho tarp with no bug protection. It would be really light. Doesn't mean I'd like it.
Just my thoughts. One setup can't please everybody...
