I own both except my 226ST is in .40 and my 229 is in 9mm (my rationale being to have the "stouter" calibre in the bigger/heavier gun to tame recoil). Both are very accurate but I was really surprised to discover that the 229 was every bit as accurate as the 226 in my hands (and I have fairly large hands, the 226 is definitely a more comfortable fit for me). While the general consensus on the 229 both here and in the US is that it is quite accurate, it might well be that the required extended barrel length on our 229s gives it just that little bit more in the accuracy department. You can't go wrong with either the 229 or the 226.
