If it's a permanently installed snake, I would rather have an analog snake. I feel it's more dependable.
At a local music venue were I often work we have an 48 channel analog snake with a monitor split and also a courtesy Cat5 cable ran from FOH. The Cat5 line rarely gets used. But its there.
Most of the bands that bring their own consoles also bring their own snakes and other cabling.
As others have mentioned, having an easy way for visiting acts to pull their own cabling to FOH would be a big plus
