Digital Solution costs and information

Trying to find best digital voyage solution for a fleet of bulkers, but so many options. Anyone know any info on pricing, advantage or disadvantages of certain ones? (BOSS. StormGeo, WNI, ZeroNorth, Coach, Deepsea, Podium5, Wartsila, or any others) Every company says they are the best, but everyone here are the end users, so more trust here.
