Been using AndOTP for months and i love that it supports android's keystore and device credentials for authentication. I had switched to it from Authy, which was quite heavy.
Aegis' design looks a lot less dense than AndOTP on the screenshots, though it seems to be widely recommended. I'll have to check what that's all about
The density is configurable in Aegis, 3 "View Modes" - Normal (what you see by default I think?), Compact and Small. You can then choose to show or hide the Account name to further reduce size, and it supports Groups to organize.
