It's not overblown. I have a less than 2 year old iPhone 6 and it has so many issues. The apps don't load or crash. When they load there is a huge delay. It's been quite painful.
Seems the problems are your apps then, have they been updated? Remove push settings, check which settings have been reset, do a cold reboot and start no apps at all. Use only Apple apps, if there are no issue anywhere in Apple's part, the problems are likely with the third party applications themselves.
