I had a similar choice a few years ago, virtual aviation for 6k or CRM Europe for 2k. I went for CRM and although I couldn’t fault the MCC training I would have been better prepared for my Jet2 sim which I failed. Quite a step up from a very basic sim to a 757 FFS - 40 hrs of 737 fixed base would have prepared me better. I believe CRM have now upgraded their sim.
