Everyone has a favorite and a least favorite. The truth is that you can learn to fly using any of the trainers on the list.
One of my favorites is the Hobbico Hobbistar 60. It is on the list in the ARF section but is also available as RTF. Here's the link to it at Tower

The primary reason it is my favorite is due to the size. It and the Nexstar are the biggest trainers I know of that available as RTF.
