Orlebar sky shorts vs sunspel thunderball remke

Hey Boys, have had the orlebars now for a while and whilst they are a favourite, they are a little faded. Was about to buy the sunspells but wondered on sizing. Has anyone got a pair of both and know if there is much difference in the size or give? I am a 34 in the orlebar and they are tailored perfectly. Any assistance would be greatly appreciated
