Ehm...why did you buy a nexus? Actually i don't even know what you are doing on xda. No offense but... Sound more like an iPhone kind a guy...

That's the biggest insult you can say to someone on XDA, calling them an iPhone guy.
Anyways. I guess my experience so far with an unrooted Nexus 5 has been so massively positive. The device is super responsive, never slugging, the battery life has actually been outstanding.
I didn't have that experience that much with the Samsung Galaxy S3, I rooted it (following tutorials and guidelines EXACTLY) from day 1 to get rid of carrier bloatware and as much fun as rooting was, it also caused me so many headaches.
So now with a device that is seemingly perfect out of the box, unlocked, direct from Google, no bloatware, I just was curious to see many people rooting a great device in it's stock state.
But these are all valid points. I might root it down the line, but right now it's so perfect, I don't want to mess with anything.
