I have both the PC version, through Steam, and the PS3 version of Dungeon Defenders.
I have maxed out the level of my Squire on PS3, and was surprised to find that on the PC I could raise skill points to a base level of 100 on my Apprentice on the PC version (the PS3 version seems to cap the skill points at a base of 70).
What other differences exist between platforms? Are the level caps the same?
