I use RPG Maker 2003 to make my games because I have the most experience with it. I have since released 3 demos and currently on my fourth game with the program and would recommand it to both newbies and people who have experience with other game making tools.
And as DrCoolSanta said, gaming making is just a hobby so enjoy it and have fun, and hopefully other people will be able to enjoy your game in the future.
Eh...
I think I've been using it since around 2004 and pretty much stuck with it. I've played around in Game Maker 6, Sphere and RMXP but still went back to RPG Maker 2003. Again, the reason why I stuck with it was because I have experience with it and just felt at ease using it, but I'm not one of those people who loves RM2k3 and slams every other maker.
I say that you should try each of th main gaming making tools at least once, spend about a day or so messing around with them and see what suits your style.
