Native.

Im terribel at making titles. But hear me out, this Twitter client is one of the most full-features Twitter clients Ive ever used. Feels native, looks alright(power more than makes up for the UI), and quick. Ive used many Mac Twitter clients(Osfoora, Twitter for Mac, Echofon, Janetter and a few others) and none of them have ALL the features I need in a Twitter client but YoruFukurou probably came the closet to perfect.

The developer is more than willing to talk to its users and loves feedback. Hes a really nice guy, too.

This Twitter client is free and ad-free. So you literally have no reason not to give it a try. And if you skip it(Like some people I know) because its "too weeaboo-ish" then your loss.
