You experience is definitely not the norm. For instance, I have Win 10 Pro X64 on two laptops and 1 Desktop. The Desktop has never been in the Insider program, both laptops were and still are.
Laptops:
Dell Inspiron 15R 5520
Toshiba Satellite A305-S6872
Desktop:
Lenovo IdeaCentre K450
I have had 0 significant problems with any of them. I run Win 10 Home at work on two systems, no problems.
One laptop was clean installed just because I wanted to do it. All the others have been upgraded as each was released.
My opinion, for what it's worth.
#1 cause of problems is hardware/drivers, especially video.
#2 is anti-virus and/or firewall software.
#3 is file system or account corruption
People who like to play with themes and modify themes seem to have a higher failure rate then people who don't.
Originally, relocating user folders was causing major problems. This seems to be fixed in the latest builds.
