Hi and welcome. I can't give you a comparison as I don't have all of them. I can say I do like my RX200s. All around good perfomers, stable TC, super ergonomic and fits beautifully in the hand, and long battery life. Known drawbacks: in-mod battery charging sux, the charger balance board is barely functional; the 510 connector is not the best, nothing you can't live with, but can be annoying; it's a 3-battery mod, so its not too pocketable. I like it, myself; that's where the long battery life comes from, and it will do an honest 200 watts on 20A batteries. It's actually smaller and not much if any heavier than a bunch of 2-battery mods, but it is thicker through the middle, plus the expense of an additional battery per charge set. At the price, get 3 or 4. You won't be disappointed.
