Oblivion's far simpler spells allowed you to make your own custom ones, while Skyrim has a far greater variety of spell designs but at the expense of spellmaking.
Personally, i prefer Skyrim's system. Spellmaking was fun and all, but at the end of the day it's just changing some numbers. As opposed to Skyrim, in which different spells actually FEEL different.
Additionally, i prefer the storyline of the mages College in Skyrim to that of the mages Guild in Oblivion. Mostly because the guilds's storyline has far less mystery and is far less flexible. Ever tried playing the mages guild questline as a hardcore necromancer?
