Blonde, start a blonde GC project and run with it later - those make some of the best looking GC out there.
But you're fronting the food bill, clean up, and raising it - so you need to go with what you prefer.
Just remember from a breeder standpoint - the Blonde will take longer time for a project to come to finish since it's a recessive gene. There is nothing wrong with a platy tiger - but if you already have the tiger gene, why add more to the same morph pool . . .
PS - prehistoric has blonde tiger / het blonde pair in the RAACA auction going on right now and ending this evening if I'm not mistaken. May be in your price range.
