What truly matters is that you have not provided a solid argument for your stance that "Windows 10 Sucks." You have stated it performs poorly compared to older operating systems. But you have not stated the configurations you used. AFAIK you may have fast startup enabled on the 8.1 Pro machine (it's on by default) but not on the Enterprise machine. That most definitely results in a significant difference between startup times. You also fail to state just how it performs poorly, aside from bootup times which can be dismissed by varying system configurations.
You also clearly stated that you base your opinions primarily on blog posts and "experiences", but have shown that you do not perform adequate research to support it (the blog posts read) nor do you open your fields of research to a wide variety of outlets to ensure a balanced knowledge base for a solid argument. You also have shown no intent to actually benchmark performance to evaluate the areas of sub-par performance for a proper "experience" to base your argument on.
It was my opinion based on my experiences and blog posts from Microsoft themselves, the one being childish here is you there, Mr. Maza!
Yes, everyone is entitled to an opinion. However when you present that opinion as an argument, it is no longer an opinion!
Lastly, your argument pertaining to the "sketchy Microsoft Store." Yes, dodgy applications do sneak by Microsoft's screening. However, the Apple App Store and Google Play have been proven to not be immune to this deficiency either. So what is your point?
Therefore, you have not presented a valid argument with solid evidence about why you believe "Windows 10 Sucks." Instead, opting to reiterate the same content with no valid support and choose to attack members who call out your deficiencies. And, moving to request the topic be shut down when you realize you're beginning to lose the argument you started. That's clearly not how it works!
Now you want a comparison, try running 10 on 2009 hardware with a 5.4k spinny disk. It performed comparatively with Windows 8.1 on that hardware with similar stock application load times and average login to usable desktop & interactable start menu. They were only obviously beat by the less intensive 7, then by Vista, and finally by Server 2k3. But that proves nothing.
