You could also use a dedicated app like Role or Roll20 for the map, and still do everything else through Comp/Con. Comp/Con is really great. I'd recommend trying that out first before using a general purpose VTT for character sheets and such, even if you use a VTT for dice rolls and for nicely formatted hex/square map grids.
Roll20, Role, Owlbear Rodeo, and Alchemy all have free options.
