If I am not mistaken, the laptop causing most of my problems was a very cheap ThinkPad from the E-series, which is not quite comparable to other models of the TP line, even when buying one of the better / more expensive ones. The one I was using shipped a very bad Wifi chip branded as Realtek. Complaints about it are all over the web (E595, Ryzen 7 with 16GB RAM in my case) This is an extreme case, but I had similar problems with other devices, albeit not as extreme. Using Wifi lead to a full connection drop for BT or vice-versa. To be fair, the offending device was a dirt cheap Windows 10 "convertible"/tablet from 2016. Other devices (e.g. cheap Android smartphones) just suffered from bad signal reach / quality / channel negotiation. Never had a smartphone with as many problems as those cheap Lenovo laptops though. I'd expect ThinkPads and other Wintel Laptops with better chipsets to be on par with apple, so yes, it's not a fair comparison. It's just not a problem that everyone has on their bullet list of criteria to choose a computer. Similar to TDP, battery replacability, trackpad quality, laptop speakers, etc
