I'd like to try the best white possible and have it on the best wood possible to support and sustain the color - a combination that works well.
If it's a solid colour, the wood doesn't make a difference. There will be enough grain filler, primer and colour coat that you'll never be able to tell what wood is under the paint, visually. If it's a transparent colour, basswood and spruce are the most neutral. Alder and ash are next, with ash being a paler colour but alder having more subtle grain, so which shows up more depends on the colour you're spraying.
Alpine/Arctic White is the purest of whites, though the clear coat will cloud and turn yellow over time, which is most obvious with this shade of white. Olympic/Ice White has a tiny hint of blue and/or purple in it, which makes the yellowing of the clear coat less obvious though it stops the white itself looking quite as bright as possible. A pearlescent white finish looks very bright when you are in direct light, and it typically has a slight blue/purple tint which lessens the yellow of aging, but it is going to be slightly metallic, which you may not want.
To get the actual purest, brightest white, I fill the grain, prime with white paint, then spray a single, light mist of a pale violet metallic paint thinned down, then spray transparent white. I finish it either with an anti-UV gloss coat or I don't spray a clear coat at all. I use poly paint, so the body stays looking bright white for far longer than any regular gloss white finish. If you have the time/means to do your own finish, and the brightest of whites is what you want, I highly recommend you try this method.
