I have used Krossover and last season we switched to HUDL. It is very beneficial for the team as you can create clips and add comments or suggestions to them and send out to your players to watch and organize those clips by positions as well. That way you can send a clip only to your defense, midfield or forwards. Your team will also have access to the games and watch those games so they will be able to watch the film. Also, you can share and ask for game film from other schools that use HUDL.
Between Krossover and HUDL, I like HUDL the best.
