Honestly, if you keep your load order light and don't use conflicting mods, the SPERG overhaul is my personal preference for Maging. With it your summons, wards, bound weapons, and spell scaling are all fixed. The perks do INTERESTING things, not just a stupid-ass 50% cost reduction. Best of all, it opens up totally new pathways for some of the underwhelming schools. Illusion has a lot of perks granting you phantasmal allies, say. Enchanting, which is boring as shit usually, now lets you do fun stuff with artifact level items. Staves can teach you unique spells, et cetera... Best part is, SPERG introduces these quality of life changes to ALL perk trees. Everything about Skyrim seems more fun with it, and the boring "level locking" perks are all auto-gain. Meaning you don't have to waste time earning perk points for Novice, Adept, etc. perks. You get them automatically as you level. Which is, you know, logical. I've tried all the rest, but I always go back to vanilla spells and SPERG. Don't need anything else.
