Longevity with SMPS is mainly down to electrolytic caps, followed by overtemperature and/or overvoltage.
Derate everything 50%, use polypropylene or ceramic caps...should be good .

I work in SMPS design - electrolytics have two things...cost and capacitance - a very good ratio between both...sadly, lifetime sucks. 10,000h is not much versus a transformer. That said, that's at 105C in the case of the KXG (United/Nippon Chemicon) series. Keep your cap at 25˚C and you're laughing. For many years. Many.

Tested/compared it with non-SMPS power supply?

I had a big SMPS power supply costing hundreds of USD made by Philips. I just destroyed it a week ago because it took up too much space
