I like that it allows me to create an account quickly without having all of my information filled out first as well! It has been very helpful so far since we started using this service from our local gym but have not found any faults yet (aside form being able use coupons more easily). Have no disadvantages at present either - just try them both before deciding which one will work best within their organization/gym type setting. Tracking memberships better between gyms; easier access into member accounts when needed across multiple locations / facilities; tracking workouts & nutrition info are some benefits realized by us currently through its usage compared to other services available.
