All three of my android phones I've owned were rooted. If you don't know what you're doing, it is possible to brick it, but it's not that likely. Definitely read a ton before you consider it. At first, I just removed all the dumb carrier bloatware and manufacturer bloatware but then I got into flashing custom roms to get as close as possible to stock android. They usually weren't that stable compared to the OEM rom so I really wouldn't recommend it on a daily driver to be honest. It was fun while it lasted but then after I started college I didn't have enough time to mess around with my phone like I used to so I stopped rooting and messing with my phones in favor or stability.
