The CPU usage comparison is cute, I can make the numbers tell the complete opposite, by clicking on Healbot for 30 seconds and not doing anything in Grid.
And I'm not even taking into account that Grid = 450kb, and Healbot = 1300kb. Generally it doesn't have real impact on the CPU usage, but you can still wonder how an addon that has half of the functionnality ot the other can take 3 times as much memory.
@Neeklus : I can understand that your biaised vision won't be changed easily. Especially if you only spend some hours setting Grid up, and not even trying it in raid action.
If you find it "buggy", it's probably because you didn't get the hang of it yet.
I can assure you that if you put a little effort, you won't ever want to go back to Healbot. Garanteed.
Don't be afraid by it's minimalistic looks, the displaying options are by far superior to any other unitframe addon.
