I'm doing the same thing as you essentially. Go with a headset that you will be giving a future passenger that you probably care about in the future, but that don't need A20s..
For me it's the David Clarks:
David Clark H10-13.4 Aviation Headset
I don't know if there is a more popular GA headset. It's also known for its build quality, longevity and is going to be more than enough for any future passengers.
Got myself a DC H10 13.4 headset just before I started training. I figured cost-wise it would be around the same to get a headset that will last a while (or go through a few cheap headsets). I have had nothing but great times with this headset.
It's aviation headset.
