Advanced vs Quick Reply

What are the differences between Advanced Post and Quick Reply?

I almost always post by Quick Reply and wondered if I'm missing a bunch of features. From what I can tell, it seems like the only difference is the ability to change the title of the post. Anything else that I'm missing?

Advanced also has the ability to hide the thread you are replying too... but is that a good enough selling point? :)

I only use it to change the title. It used to have more, but all its features have been moved to the quick reply.

Advanced is mostly just a leftover from before all the features were moved to Quick
