They’re not more reliable. I’m still using a thinkpad from 2013 as my daily driver. My work mbp failed after 6 months because dust specs got under the keyboard keys and stopped them from registering presses anymore.
I concur, I work in a department of mainly MBP15's and they have a terrible reliability experience here. The most common things that go wrong are faulty displays, keyboards and overheating issues.
I'd go far as to say the MBP15 has a design flaw where the screen breaks right in the centre where you place your fingers or thumb.
My MacBook overheated and the entire logic board had to be replaced. Apple has designed the MacBook Pro to run right on the thermal limit, but their cooling doesn't seem to work well when you run multi threaded heavy IO processes. I now have a McBrick Pro
