9831/33 or 9851/53?

[Red Rocket]

I'm looking at upgrading my head unit and have narrowed it down to the following Alpine models: 9831, 9833, 9851, and 9853. I've read tons of reviews and researched some of the pros and cons of each unit but I'd like to get some more opinions before I buy. I'm leaning more towards the 9853 (yes, I know about the Glidetouch) and then next is the 9851. I'm looking for a head unit that will allow me to control my setup a lot better and get the best possible sound out of everything.

I owned a 9833,id say its the best of the bunch,9835 being a little better feature wise - but an Excelon 889 kicked *** on the 9833 so I sold it
