If you want to do local backups via iTunes or transfer multiple large video files then USB 2.0 speeds are horrendously slow. I do both of these fairly regularly.
Luckily I can transfer videos over wifi, which is much faster than USB 2.0 speed (but still slower than transferring over USB 3.1, which I can do with an android). Backing up my phone requires I leave it there nearly all day because the transfer speeds are so slow and doing wireless backups via iTunes on Windows is broken.
