It really depends. Technically the activate is simliar. Shard of True Ice plants an ice ring that slows targets. And Twin Shadows creates two shadows that target the nearest opponent. Slowing them and revealing them for a moment. Twin Shadows has more power and gives you magic resistance but Shard of True Ice keeps the gold passive and gives the Mana regen aura which could be useful if you have a long laning phase.

I would say Shard of True Ice for a supporter. You're going to want that gold passive and philosphers stone doesn't build into anything that maintains it's gold passive so it would be wise to at least have this and turn the stone into something that will improve your mid to late game.

If you happen to be a support in role only I would say Twin shadows because someone like Volibear Support or Blitzcrank Support could get away with making Twin Shadows a very effective activate and the extra magic resistance would be a welcome addition as well.
