Apple is very expensive imo. 28 times the earnings and the expected growth is like 2%.
Microsoft is also expensive but not that much. Plus, they are less dependent on physical products like Apple meaning easier to predict future performance
Amazon has been a disappointment recently, they are trying to do too much.
Google, similar to Microsoft, seems more stable than the others and not that expensive. They also rely less on physical products however they are more prone to legislation hindrances.
Anecdotal experience but of the above companies my best experience as a consumer is with Google hands down. My work phone is an iPhone and fuck this thing is dysfunctional as hell, simply bad software design (great camera though).
Besides, my employer uses outlook for internal communications and the platform is miles worse than Google’s Gmail that is my personal
Amazon retail is a disappointment nowadays
