Default S3 still a good buy?

Hey guys

Should I rather buy a s3 or another smartphone if I want to flash a custom rom and have a reliable handy? I have a i9000 now and want a new smartphone that is faster and still has got frequent community support.
Also, I read that the european version has got an exynos chipset, is that a problem for custom rom support?

Thank you for helping!
