I would say however that the stock pickups in a lot of ibanez guitars get yanked and upgraded as soon as it leaves the box, particularly the V8s. Basically anything that isn't a fully fledged dimarzio.
You can improve the sound a lot with
pickup height adjustments and itll certainly save you money, but in the long run if you have the cash to replace the pickups you wont be dissapointed.
And in the event you sell the guitar, keep the old ones to put back in, and keep your awesome new dimarzios/duncans/emgs for another guitar!
