I wonder, do you know that you are in an Apple forum, right? What do you expect? Most people that are here love Apple and especially the Mac. I have never experienced any lag with Apple Silicon based computers. None whatsoever, even when using Handbrake to convert big video files to mp4. I had lag with Intel based Macs before. A lot actually.Whatever you get from the Mac, you can get better from windows at the same price.
I tried converting a video to webm format and my iMac sounded like it was about to explode.
My windows PC is just an i5-8400 with GTX 1050 ti and there was not even a peep when I did any kind of video editing/compression/conversion. All I had to do was replace the stock intel cooler with a cooler master and it was dead silent even under heavy load.
I also use Windows computers daily and not just what my work has given me. I used to have Microsoft's Surface Book 1 & 2 and Surface Pro and they were all awful to use. Driver issues, problems with power management, instability in the OS. It was a mess.
Windows Computers do offer better performance in gaming though. For everything else I would never ever consider to get a PC. But each to their own I guess.
