Firemaking is a nice cape, and on level with any in my opinion but: Cook-X, Fletch-X. They are also cheap to buy and quick-ish to do. I appreciate Firemakers' because they too know what's like to get a CONSTANT click 99 >_>. It's very possible to have cook, fletch, or firemaking as a favorite skill, just do what you want (I say this as Agility has been my favorite since it came out). Training beyond a 99 is purely for enjoyment for me.
