I like how it's easy for my team members as well me (as an admin)to create new objectives/goals easily without having to go through multiple steps! It also has great reporting features which are very helpful when trying to figure out what our performance was this quarter compared with last year etc.
Sometimes there could be more customization options so we don't have too many limitations but overall its pretty good because we're able to see exactly where they stand within each goal area quickly & efficiently!!
