Happy for you that you ordered a 360 Pro, the regular 360 firmware is still extremely buggy. The keycaps on the 360 Pro are quite 'meh' though. I replaced them by Kinesis PBT blanks. Still don't like the Gateron Browns as much as the Cherry Browns or Silent Reds on the KA2.
I had a chance to try regular 360 in person and to chat with Kinesis engineer. I went with Pro since I think not having cords is especially attractive in the split design. Non-pro version has a cord which is off the table (it can be replaced with the longer cord, since it’s just USB-C, but still).
I commented on the different feel of switches, and he said that it’s more economical for them to use Gateron, quality-wise it should be the same. I think I’ll get used to them.
Keycaps on Pro are different to allow light through. Since I’m unlikely to use light to preserve battery, I’ll replace then as well. In fact I’m planning to reuse some keycaps from my current Advantage 2.
Biggest surprise that there is no forward-backward tilt. He said it’s hard to make it stable and tiltable in both dimensions. I guess I’ll have to come up with some custom tilting solution - same way I’m doing for Advantage 2 right now.
I liked cushion pad a lot and going to get it to try it out, but not sure if I’m going to use it long-term or prefer more flat-out setup.
I don’t like ESC being moved, but I do like that there are new extra programmable keys in the middle.
