Wife & I've been riding recumbent 2-wheel & recumbent trikes (both tadpole & delta trikes) since 2003.
Depending on your group riding parameters, trikes can be difficult to fit in among 2-wheel upright bikes.
Low profile doesn't provide much draft for the group, possibility of catching debris kicked up by 2-wheel uprights with your face can be real concern,
keeping up with 2-wheel uprights on inclines may require some physical conditioning.
Recumbent riding position on 2-wheel or trikes allow more comfortable riding for sure.
Longer hours in the saddle and cycling over long distances become less of a physical strain.
Less neck, shoulder, arm, wrist, hand, butt and back pain when you get off the bike after a good, long ride.
Recumbents require different muscles memory that upright bikes, takes a few hundred miles to acquire or able to determine whether they are right for you.
My wife took it pretty well, since I was there to guide her along the way.
