The Turbine's look awesome! Honestly the color is about 95% of my opinion though. The same color slipstreams would look pretty similar in my eyes, and have the benefits of 19" vs 21" (price of tires, ride comfort, road noise, etc).
If I could afford it, I would do turbines in a heartbeat. They look badass. I like the older turbines to the newer ones though. The older ones looked a lot more industrial. The new ones are dainty lol.
I highly doubt you’ll get anyone saying the Slipstreams (from a pure aesthetic POV, not weight/energy consumption, etc.). That wheel is just unbecoming of the MS and is mundane IMO. I would opt for the original split-spokes if staying with 19”.
Good choice going to the Turbines! Looks great!
