There is little doubt that doing your ME/IR training on say a DA42 is far easier than something like a PA34.
You are probably a more rounded person training on the Seneca, and then doing your MCC/JOC on a glass cockpit such as 737-800 or similar complexity.

Sim rides for job interviews are often conducted on round dials.
Choose your options carefully.
