I typically have my SP3 set to 200% scaling and it doesn't change between modes. For Explorer, I set the interface to icons rather than details if I need to use it in tablet mode. I find TH2 to be just fine for everyday use, I've had almost no issues. The only reason I willingly use Edge is when YouTube videos somehow disappear in Chrome when playing full screen (I do have the H264ify extension running). The Chrome window minimizes and won't come back at all, though I can hear sound from the video.
