Can only comment on what i've tried, the derringer is a must have really - its survived its 'hype' phase and came out shining. Very easy to build on single/dual coil, grab a pom/delrin tip if pushing much past 35 watts. The sapor and lush by wotofo, super simple to set up, sapor is leak free and the lush i get barely a dribble unless it a really fierce build spraying out the afc. Both come with chuff/510 options. Dual coil only though.
Was taken back by the ephro nixon, again a cheapie with a simple build deck and good flavour.
Mute 4 is option city and hard to muck up flavour unless you whack it wide open.
Evil monk, fiddly build and you have to be cautious with the top cap but a great cheap flavour machine.
I would actively put a flavour hunter off the veloshitty, it might be good at death defying watts at which point its probably easier to drink the juice (don't) - in fairness lots of people love them, if thats their thing - crack on.
