None, I use my nose a lot before I taste food, and I'm pretty sure my nose is useful to me more than other peoples' noses are to them.
Ranking which ones are most important to me, 1 being most important:
1. Sight - I would never want to lose this, I'm very reliant on sight, kind of reflects my personality =\ Whether it may be bad, I don't know, but I can't do anything about that.
2. Feeling - I need to feel...obvious reasons.
3. Tasting & Smelling - They're linked for me
3. Hearing - Joint third lol, I would go insane, seriously, insane with nothing coming through my ears. I leave the fan on overnight, winter/summer/autumn/spring, w.e. because of the noise it creates.
