In the very long run, would you say Archery or Destruction is most lasting fun for you? Is Destruction more versatile?
Or is Archery more versatile if you add Alchemy to it with Poisons and such crazy stuff, or Illusion? Which?
Still Destruction more versatile, therefor more lasting fun? Nontheless damage outsputs, etc, speak.

Destruction. Enemies get too close? Choose one of the shroud spells (which pretty much deal AOE over a given time damage to enemies near you.) Frost spells tend to slow, fire spells increase damage recived AND deal DoT, Lighting spells sap an opponent's magicka. Dual casting can improve/overcharge spells, increasing damage output.

In contrast, the archery perk tree, consists of either making it better for you hitting your enemie or for recovering your arrows/run speed. Can Knock Down enemies, increase critical hits, and steadies your aim... but you require other disciplines to create additional effects that may help in certian situations, such as elemental weaknesses.

For me, throwing weapons or archery because they provides the most customization with enchantments, then poisons, and now smithing. In my opinion destruction is the most basic form of magic. Alteration and Illusion is when you can really have fun. paralyze is my favorite spell.

Without spell making, there's really no reason to choose destruction over archery in my opinion,

I love archery.
I think there is more ways to go about a pure archer than a pure destruction mage.
Destruction doesn't get any sneak attack damage where as archery does.
Theres more benefits to archery than destruction with poisons,quick shot,steady aim,deadly aim and power shot,plus all the overdraw perks.

I'll let the mages argue for the destruction side.

Archery hands down. Destruction really svcks at higher levels.

Destruction is my favourite. I love elemental magic. I just wish there was more.

I prefer Archery myself, since it's not tied to a limited resource. It is, however, easily made grossly OP, so every so often I go Destruction instead for a change of pace.
