I've had just enough wine to make me think I can intelligently contribute to this conversation.
From the two videos, it seems to me the Fox design is simpler and a lot more elegant, whereas the Bilstein version relies on extra bits at the top and bottoms, bits that could break/fail. Oftentimes, simpler is better.
Now, I'm totally talking out my back-side, and I have no real-world experience, but I did just watch those two videos above, sooooo I'm basically a PHD.
......and I stayed at a Holiday Inn last night.
