Best dropper seatpost Rock Shox vs X-Fusion vs Brand-x

I'm in a position where I have 3 different 150mm internal or "stealth" dropper posts, so I thought I'd make a quick video with my thoughts on each.
So which is the "best" dropper seat post (Is there a BEST?)...
RockShox Reverb
X Fusion Manic
Brand X Ascend ........
