Come on Twirly you ain't that green
Whats considered best, is as with most things a matter of personal preference.
Some people swear that the rose is the best or the UTA/UTA2, I personally think that most attys are over complicated and gimmicky.
I exclusively used one of my own (a mesh genny) and a Spheroid for over a year because they were/are trouble free with no gimmicks IMO.
At the moment I'm using a Merkava from mini e-cig (£65), adjustable air flow and juice control and it just works, flawlessly(really impressed with it) very simple yet clever design.
For me keeping it simple is key, also setting up properly and knowing what works best with your gear i.e mod ,juice, ohms and wicking materials.
Trial and error, but all part of the fun!

I really dont like messing about)
