Whatever you get, you might want to ask the seller if either size has a rim protector. Tire manufacturers will often use different terms to "rim protector" but it's all the same thing. It's extra rubber moulded into the sidewall that is supposed to help protect the rims from kerbing damage, but often they are not very effective unless you use a minimum rim width for that tire size. By using a minimum rim width for a particular tire size the tire's sidewalls will bulge out more so that if you gently graze a kerb you might get away without damaging the rims.
I don't like rim protectors and try to purchase tires without rim protectors. The reason being that they make the sidewalls flex less easily and therefore make the ride harder. This is however disputed by the tire manufacturers who will often claim that thick rubber rim protectors moulded into the sidewall will make no difference to ride comfort. I suspect that this is just PR on their part so that it doesn't affect their sales.
