alt Hacker NewsI'm always a little cautious about "tried it in the store" experience. If I nuke and rebuild my machine (either Linux, or Windows), it's always significantly faster than it was before. Over time stuff just tends to accumulate that you don't notice. Like the old days of needing to defrag hard disks.

Yeah, same - I tried the M5 Pro randomly while waiting for my daughter to finish salivating over a Neo, and just got surprised by how quickly it opened apps and reacted to anything I did - ~1-1.5 seconds for Affinity Designer was amazing.
My MBP probably got affected by OS updates like other people are saying - opening apps and responsiveness definitely got worse, and felt like slightly deteriorating over time (but it might have been MacOS updates along the way).
I agree with you that this is a noticeable effect, but I have a hard time figuring out why it is, especially on Macs with the sealed system volume (which should make the operating system files bit-for-bit identical between a freshly set up Mac and one you've been using for years). Certainly it could come from the accumulation of cruft in /Library and ~/Library, but you can clean that up too.
