As a Gitlab CE user and part of a large company using Gerrit for code reviews I am really surprised that Gitlab does not try to emulate a bit more the various enterprise grade Gerrit features available such as full side-by-side diffs with key shortcuts, review history to easily see what changed since the last time you reviewed the merge request (even with rebased commits), +1/+2 rules, custom plugins available... Etc.

I know that Gitlab EE has some features like the merge request rebase, but I don't know how a large company using gerrit could be convinced to switch to reviews in Gitlab

We would love to add features like that. We have side-by-side diffs and shortcuts, but maybe not what you want. New commits are shown in the discussion (doesn't work with rebasing). You can have approvers for merge requests https://about.gitlab.com/2015/06/16/feature-highlight-approv... and we support project services http://doc.gitlab.com/ce/integration/README.html

Anyway, I'm sure that there are still things missing and you are very welcome to add them to CE or EE. We had large companies switch from Gerrit but we hope to keep adding features that people currently miss.
