Theres a whole heap of software used around here. People tend to settle down with one or two apps after a while and get a style which sticks with them. I guess its better to use what you know and progress it rather than take the hit of learning something new. Sometimes its the unusual tools which makes for a style which is also unusual and therefore distinct and interesting. If your new then I would suggest looking around until you find styles you like and then finding out what apps created them and see if they all point in the same direction.
