Cluster is amazing for anyone who aoe heals. It will have an icon and show the number of people your aoe heal will hit based on how close they are to each other. It just helps to get the max number of people hit.
The comp to server lag has to do with spells along with player updates. Especially in 25s grid and more specifically healbot are a lot slower to update. Most of the time when it comes to spell casts it is small, but it does make a difference by the end of a fight.
The main reason I switched from grid(when I really really didn't want to) was because of those few things and updates. Vuhdo is one addon which makes it so everything is updated at the same time. It also is always updated pre-patch and ready on patch day bugless. Once I started using it(mid wrath) it already had a large following, enough to where the developer is pretty much amazing when it comes to keeping it up. I've never once had it bug or break unlike my grid and healbot.
If you don't mind taking time to set addons up, it's worth the change for any class. And if you really love your grid you can set it up the same exact way just with the extra options.
