I had both.. Ditched the aerohead and I'm using the POC. I couldn't race with the aerohead because of fogging issues. POC also has better visibility if you have a lower head position.
Tried defogging solution, rainx etc.. Didn't work for me. It's also hot AF and heavy. Too bad because it suited my position pretty well. I'd be willing to try it again for racing in dryer conditions. Unfortunately in South Florida mornings are 90% humidity or more.
What's your CdA?
