JackMurphy I want to know
Have a search through the already many duplicate threads on this topic and perhaps commenting in one of them, as community members with experience and/or developers/team members from Molly would be following those established threads. For example, https://discuss.grapheneos.org/d/8976-signal-vs-molly-vs-molly-foss/ mentions exploits, webrtc, etc.
As for comparisons of the source codes, maybe check out their matrix community space/room and search for prior discussions or their github issue tracker, etc.
