As salamu alikum.
I agree with pangloong. Normally none should compare in this way. I think each company targets a part of the market not the whole. It is also quiet impossible; because the main target of microcontrollers are to use for particular job.
So, when you have the target and when you know the IOs, ADC, PWM, USB, and other ports you need then you would search a particular microcontroller for your job. That would be made by any company.
From my little experience I saw that sometimes unknown company provides the perfect solution for a particular job.
