The Pre-touchbar Retina Macbook Pros were the perfect laptop for the era. They could run a bit hot (but what didn't, back then?). Excellent hardware quality, and can generally still run well today if you don't do anything demanding. I've got a 2013 13" that doesn't have a single issue other than age.
The heat and constant fan noise was a real problem.
That's the entire reason we upgraded my wife from a 2015 15" MBP i7 to a 2020 MBA M1. The extra hours of battery was a nice bonus, the main gain was the lack of noise.
