I've seen these okay-ish numbers, but subjectively it was a crap experience (bad enough to buy an SE). It wasn't really app launch times that bothered me, though. Scrolling all around the OS "felt" (not sure how to measure it) like it was running way below 60 FPS, whereas everything was buttery smooth on iOS 10. And the OS seemed to only keep one or two apps in memory, ever. I suspect it might be because I only had 1GB of free storage, and iOS 11 was uploading and downloading cloud photos like crazy? Often I would take a picture, and by the time I wanted to send it via message ten seconds later, the phone had deleted the original it from my phone, and had to re-download it. I would gladly assume that I'm an outlier, but a friend with a 5s asked me for new phone recommendations right after updating to iOS 11, so there's at least two points of anecdata.
