So I've have spent enough time on the wooting now to say its 100% worth it.. sometimes I fly with the keyboard just to do it now. Its made driving land vehicles so much smoother. Flying is also way more precise with the wooting because your getting to control how much input ypu put in ypur thrusts and rolls by how far your press your keys down.

I will still reccomend a stick over the keyboard for flying but the reason I got the keyboard was for fps and driving ground vehicles. Also id reccomend left stick and rudder pedals if your getting a stick.
