Features is a widely used module and can be very useful, but I am personally not fond of it. I find it somewhat bulky, cumbersome and on a small to medium build it seems overkill. I also dislike the thought of having more modules/code than I need in a build and being unable to disable and remove a features module without removing the functionality bugs me. There are those that swear by it and wouldn’t dream of developing or maintaining a site without it but I am not one of them.
