I've just received the byLeo Sophia RBA for use in a titanide slim tank and microstick (for a stealth setup) and so far it seems very impressive. Flavour is excellent, it doesn't leak, has easy juice-flow control by turning the drip tip and you can quickly swap out the ceramic cup/wick and coil without draining the tank. It has trapezoid threads so it doesn't slice up the wick as you adjust the juice control. Seems to be a really well thought-out simple mod that works very well.
If I were to buy a RBA I'd get the byLeo Sophia or the GP spheroid. Both look like simple, relatively faff-free rebuildables that work very well.
