is their a huge diference between the Prs se standard and custom or is it just looks

i like the standards looks alot better and it's way cheaper so i'ld really prefer that cosmeticly
but if the tonal difference is signifigant enough i'ld pay extra for the custom

Not necessarily a better sound but the Standard will be a little darker and muddier than the Custom - for most rock styles a mahogany/maple combination is preferred. It is a tone difference but no one of quality so much as one of personal preference. I suggest you try them both out and decide for yourself.
