Golden cheetah, what am I missing?

stueys

Started playing around with power software so I can analyse my rides better. So far I'm comparing a trial of training peaks athlete edition and golden cheetah. Training peaks gives you a nice view of diary, planned training etc which golden cheetah doesn't but I have to say I prefer the look and feel of GC and I'm struggling to see what it misses I'm terms of analysis.

So considering its free and trainingpeaks isn't, am I missing something?
