@bolkow: In my opinion the EC-145 has the better avionics and the more modern Cockpit layout. I like the Autopilot of the EC very much. It provides you more space, more power and a greater endurance.
A few years ago the EMS fleet in Germany operated a mix of MD and EC Helicopters. Now the MD´s are all gone they were replaced also with EC´s.
People which flew both the EC 145 and the MD Explorer tell me that they prefer the EC-145.
I have never tested the Explorer myself but I´m satisfied with the EC-145.
