Familiarity: I've put it through the wringer
I bought a Turbine to avoid the issues friends are facing with their hydraulic-actuated droppers. It has no hose to bleed, and when it malfunctions, you can still ride it home. In a nutshell, it's a decent post, but it comes with its own unique problems.
First, setup was not easy. Despite proper cable tension, after the first ride, I couldn't get the seat to lock in the down position. Two visits to my local shop, four re-installs, one brand new cable, and still no fix. I was on the verge of warrantying it until midway through the next ride, when it miraculously started working again. Six or seven rides later, it seems to be working great, and I'm keeping my fingers crossed that it was just a break-in issue.
Second, the return speed seems to be the same (fast!) no matter what air pressure is in the post. Range is from 20-40; I have 22psi in mine and it still shoots up like it wants to punch me where it counts.
Third, the stock remote lever is awkward to actuate and impossible to mount in a comfortable, non-exposed position. I'm looking at the 1x lever, but dreading the hassle of reinstalling the cable on top of the $60 expense.
Would I buy it again? Maybe, since all I hear are horror stories about every other post. I don't understand why, with a dozen manufacturers out there, nobody seems to make a post that doesn't break (KS) doesn't cost a mint (Thom$$$on) doesn't ask for $200 of rebuilds (Reverb) per season, and has a decent lever. So, to sum it up, this is the best dropper post for me - no come without issues, you just need to decide what you are willing to sacrifice.
