My only other RTA I have is the Pharoah Mini, so I'll be mostly comparing to it.
Flavor is excellent, on par or maybe even slightly better.
Easier to disassemble
Much better air flow, but loud at all settings.
Much better capacity options vs Pharoah Mini, you don't have to sacrifice flavor with the bubble tank.
Top fill on the Kylin is noticeably easier with 2 larger kidney fill holes
Would say it's harder to place wicks, but not as hard to get right.
Pharoah has better coil connections and much better build quality.
I enjoy both tanks, I slightly prefer the Kylin cause it's easier to clean/wick/coil/fill.
