Only you can decide if the issues you have with your nose warrant you incurring the risks, recovery, and expense of a revision procedure. I think it should not be up to surgeon to decide on the aesthetic "need". It has to come from you.
No doubt your nose was imperfect prior to your first surgery and it seems you think it continues to be imperfect now. Hopefully, you believe there have been improvements that resulted. If you truly are unhappy with the outcome and feel the degree of dissatisfaction would warrant another procedure, then I would advise that you do your homework for a good revision specialist and seek a consultation.
I am concerned that you said 3 surgeons have advised against revision, however. This could be an aesthetic judgment on their part (which I cannot provide based on the single angle view you provide). Or it could be a sense that they cannot achieve the specific goals that you are seeking.
Either way, that should be a red flag against pushing for surgery. If you opt not to do a revision, you have to shift your thinking from "how can I make my nose better" to "how can I be comfortable with the nose that i have."
