This series of tests compares my older G1228 with the Feisol 3442. All images with all 4 legs extended to full height.

The Feisol performs fully as well as the Gitzo and an argument could even be made that here the Feisol outperforms the Gitzo. Having the benefit of getting blurry eyed studying over 400 controlled test images of these two legs, I would just call it a dead heat and leave it at that.
