Touch is the most dangerous to loose, because you could have your skin broken, or a nail put thru you, for months and never know. Imagine not knowing if what you were touching was hot or cold or physically damaging your body?
Smell doesn't make much sense to give up, because like half your taste comes from smell. You're effectively giving up 2 senses for the price of one.
Sight and hearing I simply couldn't imagine losing tbh. It's a whole other world; although I'd rather lose hearing between the two in our increasingly sight/tech reliant world.
Taste seems to be the most practical and efficient to give up, to both minimize loss and improve longevity.
