Few people report issues with any of several stainless rods. But fewer still report issues with the Glock recoil spring assembly. For reliability I opt for the Glock.
If I could only have one it would definitely be night sights. And if I have a light mounted on the gun I use it as a secondary light. Some people really dislike having a gun pointed at them because the light attached to it was pointed at them.
I never talked to anyone who had to fire their gun who said "I wished I had the smaller gun and fewer rounds with me" Just because you find a hundred people who agree with you on the internet does not mean you're right.
