Hi Maasa,
I was absolutely terrified to try the JPouch, but I am super happy that I did. The ostomy bag worked well for me, but I thought - let me try for the JPouch, and I could always go back to the bag if the JPouch fails (although that is not simple to do). For me, I just liked the freedom of not having to to wear an appliance. If you do pull the trigger - go to someone that does a lot of pouches. A center of excellence that specializes in Jpouch.
