I have both! I have Ipe decking that looks a bit like the picture below, leading on to York stone. To be honest, the decking is far more slippery when wet than the stone, which is grippy no matter the weather (well, apart from snow!!). Neither the decking nor the york stone get too hot.
I agree that the old fashioned grooved decking is a bit cheap & cheerful, but you can get some really smart decking now - they also do a composite version of Ipe which you don't need to oil every year.
