which should you pick?

Choose Synergy if you need first-class Linux support and paid commercial support, and don't mind the license fee.
Synergy is a mature, respected product — its open core (Deskflow) is excellent. ShareClick is the newer, free-and-open option focused on Mac↔Windows with a UDP input path (~6 µs transport overhead), encryption on every channel, and zero-config mDNS discovery.
