Thank you guys for your inputs !
G-Dubs : It's already what I have

robbles : Interesting article. I had never heard of those switch before, but they definitely seem interesting. A custom keyboard seems to be quite an expensive option, but I'll definitely try one day, just for the fun of the build itself as well as having MY keyboard

Since last time, I decided to give myself some time to think about it. I decided to stop comparing my Matias switches to the Clears and just start to think of it as a different experience. While I do love the soft bump and springiness on my Clears, I'm starting to find enjoyment in the snappiness of the Matias. I did some serious typing in the past few days, and I am getting back to my old speed. I guess I must have been going through my "what the f***"-phase, since it's only my second experience with a MK and the tactility of Matias switches is nothing like the Clear's.
I also went for a towel "mod" (actually T-shirt "mod", I don't have any spare towel

). Quite the upgrade to me. It feels great, it seems to make bottoming out softer, and it also makes the keyboard delightfully silent ! The resonating desk was seriously annoying, strangely it did not bother nearly as much with the Clears (which were much more noisy). Must have been the more metallic sound.
For now, I think I'll be sticking with my Matias, see how much I enjoy it in the long run, but your inputs are definitely invaluable !
