See for me it's the other way around. With DHL who knows when it'll arrive or if the driver will even attempt to deliver your item. (Currently, I have the problem of DHL claims something was delivered yet the front office says it wasn't.) DHL massively overwork their drivers, which results in them having far too many packages to deliver, therefore just end up dropping them off at a local post office for pick up.

Amazon Logistics, it arrives constantly. Also in the UK Amazon Logistics even deliver prime items on a Sunday - also in the UK they send a lot of items with a few amazingly crap delivery service so when you get Amazon Logistics, DPD, or Royal Mail, it's happy days.
