I live in the Gulf Coast and it has gone through Monsoons, high water, Moab dust, East Tx clay, North Texas snow etc....They are still quiet. I do clean and lube them a minimum of once a month. My UCAs are also heim joint, and that make a little noise if the windows are down and radio off.
I did notice, a week in snow (the melting agent they use on the road), would be an issue if I had to live in that. All the gouges on my skids showed rust in days. I assume it would be just as corrosive to a Uniball over time.
For forest roads, just go ball joint UCA. And I'd definitely skip heim joints....
