You prefer a 100% or Shiny?

A friend of mine has a 100% Shiny Aron

Well i prefer my 100% Mewtwo over any shiny or 100% shiny aron

I prefer 100% meta/favorite mons over any shiny. Shinies are nice, but they're just collectibles. 100% mon can be collectibles AND useful.
That said I would go nuts for shiny Eevee.

Wonder shiny Magikarp.

I think most shinies are either uglier than or barely distinguishable from their ordinary counterparts. So generally speaking, I'd much rather have a high level catch with high IVs.

For the top tier stuff? 100%. For bottom stuff? Shiny. Though I do want to have 100% on normal and 100% on shiny since I am a collector and have that 1 of each form rule.

Neirher!
I prefer maxed out ones
Rather a lvl 40 one with IV 11% than a shiny 100% at lvl 20.

100% for me. The only shiney I care about is Gyarados. Most other shinies aren't particularly distinguishable or iconic. I'd rather have the best possible of that mon.
