AMP was one of the things that pushed me off Google search and off Google Chrome on Android. The experience was mostly worse; especially reddit AMP is really awful, even given how awful non-AMP reddit is.

The few things that bothered me the worst were, blank white pages while loading, to earn the 'one contentful paint'; fonts loading late; and it's difficult to share links, because they had the garbage urls because google was proxying. The fake address bar was the icing on the cake.
