EbonJaeger I agree, from my experience, no other Chromium-based browser comes close to Edge's performance and stability, regardless of OS and hardware (I have been testing it on Windows (installed the enterprise version) for a very long time). It also hands-down beat Chromium in every way possible, and for places where Chrome was installed (not by me), it also made Chrome feel like a sloth.
That said, while there are hiccups here and there (certain websites fail to properly load, though that could be a result of my strict privacy settings), my time with the Edge preview is simply fantastic.
No issues scrolling, that's for one, and the performance is way better than both Firefox Nightly and Vivaldi Dev, over here, plus, overall, less issues with websites (Firefox Nightly has CSS bugs the past two cycles, though, other than that, I have always had less website breakage with my strict privacy settings on Firefox than Vivaldi).
Hardware acceleration is working great here, though I had to toggle a few flags as a result of my old hardware (Radeon HD 6950). Only hardware acceleration for video is currently unavailable.
As for system resource utilization, I was astounded to see Edge using much less system resources (CPU, GPU, RAM, and storage (on a 7200RPM HDD) than either Firefox or Vivaldi (and I have more extensions on Edge than on Vivaldi), and keeping it that way, even with a few tens of tabs open at the same time (80MB of RAM at startup, and between 80-140MB after extended usage, depending on how many things are open).
I still prefer Firefox, however with the breaking bugs it is facing currently (Stable users wont be seeing this for quite some time, unless they manage to fix the issues), I may need to delegate it to being my secondary browser, with Edge as my primary.
