personally my favorite turtles are the ones from the original 80s/90s cartoons. my 2nd favorite versions of them are the ones from the movies (except number 3, lol)
The only reason I was kinda disappointed in the worlds in the movies was because they didn't take such a sci-fi approach to it as the original cartoons did. The movie avoided a lot of the inexplicable things from the cartoon like Bebop and Rocksteady altogether, the foot soldiers as robots, Krang, Dimension X, The Mousers, Baxter, Rat King, etc etc etc etc... and the list goes on.
They shoulda made the movies more like the original cartoon IMHO, but then again I still love the movies for what they are and I will always love them because they were well made regardless of their flaws. But the original cartoon will always be my favorite interpretation of the green ninja boys.
