I'm using Amethyst and Nostrudel. Unfortunately I don't owon an iOS device otherwise I would certainly try Damus. 
To be fair I can switch between Global and Following "top-level views" but the "following" view still displays everyone’s comments on both clients. My best option as a user is to stop reading from certain public relays under attack until the spam settles down. If I could select an option to display only comments from "followers of followers" or maybe 3rd-degree connections, most of the spam would be gone. Then, I could quickly disable it to welcome new users, etc. This would definitely be a much better user experience.
