If A.Net would come out and say that the gear we have now will always be the best gear available, then I'd go with ascended stuff. But since they haven't, and I imagine better gear will be available, I'll probably just waste the laurels on dye.
I have a similar kind of paralysis. I don't play enough to accrue many laurels at the moment for various reasons, but with every update there seems to be some new currency or new stat combination or whatever, and after the bait-and-switch that was Ascended gear, I don't trust Anet not to come out with some other optimal piece of equipment to buy next month. I don't honestly know what to spend my hard-earned laurels on because whatever I spend it on, I'll probably wind up gimping myself and wishing I'd held onto them.
So they sit there, accumulating, and I don't spend them at all Alas.
