I respect that. I would still be dubious about your DS experience on this device. I have the 3B and love it but even with more buttons I shy away from DS.

Definitely go for the bigger screen and don't expect ergonomic feel. It seems like the cases of both waveshare kits are designed to cramp your hands.
