Brian304,
It's very rare to find someone that has done their ATPL theory at more than one training provider!! Especially on a full time course. My advice is to visit both (or any of the schools mentioned above), talk to current students and see what the atmosphere of each place is like. What suits one person may not suit another. A big consideration for me when i did mine was the commute as i was not in a position at the time to afford to stay on site. In the event i ended up doing Distance Learning anyway!
Hope this helps
