I am like you, and I think it might even be worse.
I like to tap tweets on the official app and view the whole conversation (people's replies, etc.), but that doesn't seem to work in Tweetbot. In Tweetbot, you have to tap the tweet, then tap this small gear icon on the right, then select "view details" to get the same result as simply tapping the tweet in the official app.
It also seems to be completely impossible to do any kind of text selection in Tweetbot.
I've been messing around with it, but I'm not seeing anything that makes it better than the official Twitter app for my personal uses, which don't include very much replying or retweeting.
I do like how it shows hashtags in a differently colored font, though.
