I've not run those de-bloaters, but I checked one that scanned what could be done with 11, and I had managed to kill most of the bloat even without running it, but even that did not improve the performance. It even takes a lot of effort and needs to be repeated constantly, since the damn shit tries to install everything back with every update. Win10 is a bit more merciful in that regard as well, so despite "downgrading" it really feels like I upgraded this thing instead.
I'd really prefer something like Zorin, I got the memory consumption to 1,5 gb at it's lowest when I tried intentionally, which is pretty impressive with the visuals I could still keep. I'd also rather not to have anything microslop-build, but sadly SP's are still pretty much the only option available that's small enough to really work as a tablet, has good enough pen sensitivity for drawing, but still works as a proper computer... I would never buy anything after SP9 though, it's all some copilot infested shit.
