That is quite scary! I think I've had 90 or so shaves with a Feather in that time, but I'm using it less and less. I wanted a nice big thorny problem to solve during lockdown, and I was definitely entertained by learning for a good while there.
The culmination of the project for me is that I discovered that there are very few blades I like in the Feather handles. I almost bought a Kai handle, but didn't. I almost bought a straight, but didn't. My interest has started to wane a bit, not just in the Feathers, but also in shaving in general. I've been around the block enough times to know that it will be resurgent at some point, and I'll no doubt take it up again.
As for DX vs SS, I personally don't think it's a decision worth wasting much time over. They both feel really well made to me, but the DX is heavier. That's about it. As I never transitioned to a proper straight, I couldn't tell you whether the DX is truly closer to the straight experience.
