Sight is the most important to me - there are simply too many beautiful things in this world to go without seeing it. I've always loved staring at anything that just randomly strikes me as visually appealing

Touch is next - I use touch to communicate a lot irl, where words don't seem to come to me as easily as when I'm typing. Touch is extremely important in relationships, both in and out of the bedroom, it can convey a lot that words cannot, and can have a much more profound impact on someone.
Hearing is third - hearing gives early warnings of things that your other senses won't catch, and is key to detecting subtleties in verbal communications. Sarcasm and emotion are extremely numbed when you can't hear the intonation of a person's voice (re: it's a hell of a lot easier to miscommunicate when you only have words to go off of)
Taste is fourth - taste is pleasure. Without taste, eating would be just another mundane daily activity that wastes away your life. Taste is key in detecting harmful substances before they are fully consumed (re: something that tastes unusual is usually spit out).
Finally, smell - smell, while useful, doesn't do much that other senses can't, and is often more harmful than beneficial, especially with the relatively weak sense of smell that humans are born with. Foul odors can generate physical ailments (nausea, queasiness, dizziness, even vomiting), though some people claim that certain odors can bring minor medical benefits. Without smell, nobody would need deodorant f3
