For my fleet, I wanted a standardized uniform that gave homage to the ones seen on-screen. I polled my fleet members with these:
They all use the Sierra-1 uniform (since Fleet unis require "free" items and you can't use anything that must be bought or unlocked. The second row were the options, with the top row being the canon uni's that were being paid homage to. Type 4 also pays tribute to TOS, but it's primary inspiration was AGT.
