which company's product has great UX? I'm always seeing people hating on things without showcasing examples of what they think is exemplary
None. A great UX nowadays is open source software running on your own hardware. For example, you couldn't pay me to use a "webmail" like GMail over my own IMAP server and Thunderbird.
I do it for autonomy and avoiding lock-in, but Thunderbird has some frustrating inconsistencies particularly in its mishmash of searching and filtering.
