I think no IM has topped the MkVII because none of the Iron Man armors shown on film after the Avengers featured so many features on the screen. The MKVII was armed to the teeth and had some cool features on the movie. The IP/WM2.0 and MkXLII don't nearly show-off as much in Iron Man 3.
Totally agree, the MKVII is way better in terms of features, the MK42 has to be the worst one, it seems like it was some sort of joke armor, it almost never performed properly. The only thing it did correctly was blow up and Killian still survived! and even if it didn't crash and Tony got to wear it fighting Killian the he would had died for sure, stupid prehensile crap!
