I hate windows so Microsoft is out. Really miserable considering Apple and Linux.
I recently upgraded to a Mac for the first time in my life and it is very nice. Apple hardware is pretty good but the software is kind of annoying. They've done great at extracting and defending their moat but there is no real ecosystem growth.
I use Google Login for everything and pixel phones. They're lagging but I think Google is the most well rounded and best capitalized going forward. Really difficult to commit to someone else without accepting pretty steep limitations. Google is setup well here and hasn't been afraid of expanding the ecosystem even if rollouts are lacking vs the best in class. Maybe you give up peak in specific sub categories but Google is the least annoying across every ecosystem sub category.
