JohnnyCI own both. Both are great. You really can't go wrong with either.
However, here are some difference: 1. The Retrakt (aluminum) has a more matte finish compared to the Tactile Turn - don't know if it's because I've had it longer. 2. The Retrakt sticks out a bit more if you're using the clip. The Tactile Turn's clip is higher and consequently it "hides" more when clipped. 3. The Retrakt is very smooth -- the Tactile Turn has the grip section which can help with the grip of the pen.
Again both are great, I own both and use both regularly.
JohnnyCI've never tried the jetstream refill with the Retrakt. But according to Kara's Kustom kickstarter page on the Retrakt: "

Jeff,
Any refill that is compatible with the G2 or Parker Ballpoint should work just fine. I just put a Jetstream refill into the Retrakt with the spring designed for use with the G2 (we give you two different springs) and it looks like it should work fine after it is "massaged" a little. Many of the G2 "compatible" refills are a little longer or shorter and require just a little tweaking to fit. Longer ones get trimmed slightly and we include material for customizing a spacer. While not ideal, it allows for different refills to still work with the Retrakt. If it fits into the bore of the barrel, you can pretty much get it to work (as long as it's a retractable type of refill) with major modifications. Does this make sense? We are thinking about making a video explaining this in more depth, if there is enough interest."
