Anyone doing a modular course, ASG is the best option. Obviously i cant compare directly as i never experienced ATPL theory anywhere else, but through friends studying at other ATO’s speaking of theory experience, ASG outperforms in all sectors. 

Instructors mostly have military background, well trained and kept up to date and always very welcoming about asking them questions at any time.

Although based in Ireland for myself, there was a few other students from many other countries in Europe and all seemed to have the same positive experience.
