Ok this is a rough outline of what i can see people are saying
Twin star
Pros: Higher pass rates, reduces pilot workload and makes the IR simpler and introduces the pilot to the glass cockpit
Cons: Doesn't prepare you If things go wrong, more expensive, takes time to get used to the screens.
Analogue
Pros: Prepares you for if/when the FMC fails, Airlines like it better, Cheaper
Cons: More Pilot workload, the transition to glass on the flightdeck is more difficult
