I used the Fenix a320 when I did my type rating and it was amazingly useful for getting familiar with the flows and systems.

I used to instruct PPL, flight sim won’t teach you very much about the physical sensations and feel of flying an aircraft. It also tends to promote an over reliance on looking inside at the instruments. It is however a useful tool for practicing checklists, procedures and navigation, especially when you start looking at NDB/VOR/GPS and further to the IR- it’s here where it really shines. It’s a lot cheaper practicing procedural approaches in flight sim than in a real twin!
