Mac vs Surface vs Chromebook

In the last 15 years I have only used the laptop issued by the organizations I worked with (MacBook all through). Given a lot of scrutiny and snooping by employers on devices issued by them (they have all the right to do so, not questioning that), I’m planning to purchase one for my personal use. I’m out of touch with the gadget news, so looking for some suggestions on which one to go for - MacBook, Surface, Chromebook.

I don’t use any OS specific apps - all the work I do is on cloud apps.

Looking for something that I can use for next 7 years at least, without any worry about performance degradation.
