I use both, and one thing I found that is sucky about WG is that it does not work well with the Windows firewall. I need to give full permission to an app to be able to access ip addresses routed by WG. Tinc does not have this problem.
One thing I noticed with tinc is that it does not take advantage of sysctl network tuning. I had to increase the network buffers for that dynamic routing to not make as much of a noticeable slowdown.
