I like how easy it is for me as an administrator in my church/ministry organization, because everything seems so intuitively organized that way! It's also very user friendly when you're working with other staff members or volunteers who are new at using this system (and sometimes not even computer savvy).
There isn't much dislike about anything specific; however there have been times where we've had issues logging into our account from another device than what was originally used during set up - usually just happens once every few months but can be frustrating if your team uses multiple devices throughout their work days each week (which most do!). We use quickworhip primarily through email communication between myself & others within ministry leadership teams since everyone has access via mobile phones / laptops etc., which makes things easier while out doing outreach events around town rather then having people come back later after they get home.
