Steam or glass
I own and operate skydiving aircraft with steam gauges and fly a two seater with full glass. I would always go for the glass instruments but I don't think you would get your money back if you changed from analog. They will both work for you. I think long term glass will be less likely to let you down in my mind electronics tend to fail early or not at all. Good luck with your choice just remember for skydiving keep it simple.
