My logic behind a decision such as you are about to make is this. Did you go cheap/cut corners with any stage of the many mods you have done to date? I think not mate.
The exterior of the car is, rightly or wrongly, how people ultimately judge how "good" a car is.
Based on your thoughts in this thread, it suggests to me you want your car to look good (as most of us do).
IMO your car only deserves a proper paint job, not a "blow over". Don't even consider anything but the finish it deserves. You haven't gone cheap at any stage, so don't break the chain.
I would wait till next year so you can show it off in all its glory during the summer months.
