I liked it once I set the article style to super compact. Block list is really nice too if you have a rss that throws in unrelated material from time to time like ads disguised as articles.
i personally like feedme - it's not m3 as asked in the op, but it's the most feature-filled android client that i could find, that syncs with inoreader
After a few attempts with different apps I've found Nextcloud News works well for me and it syncs to my self hosted Nextcloud server. Which I can also sync with desktop apps.
