Like the Brown $20 over the Lavender $25 (surprise, surprise).
But I think it all boils down to whether you want a $20 chip or a $25 chip. If you want a $25 chip then the Lavender is the best color choice. (especially for a cali color set) And I don't like a Lavender $20 at all, Brown for a $20 chip, plus it is a better fit with that $5 (which is killer).
