High five for joining in on the fun, @Big_T! Of course this entire hobby is personal - both the conditions of one's person and one's personal preferences.
I've only had one shave with the Athena-halo and for me it was worlds better. I have to give it a lot more tries though. I didn't have to focus on offsetting the top-heaviness of the razor and I had a much better grip with the o-rings. I could relax and really enjoy the shave. The Athena head is terrific, I still get all the smoothness and efficiency out of it. I love the looks of the Athena with its handle, it is gorgeous. But I never found the handle to be functionally better. On the other hand, the head is functionally better than most razor heads I've used.
