This is a lot like asking "which is better, ford or chevy?"
My two cents, and I have turfs, is if you are going to be working a LOT in dirt with the FEL or ground engaging equipment, ags (or bar) would be better. They will self clean and provide more UMPH.
If you have turfs and get in mud, they will fill up and you'll have slicks, which won't work at all well. I've not had to work in mud, and my turfs seem to hug the ground well when I pull the box blade. When the going is tough, I'm in 4WD and often will scoop up a load of soil in the FEL to add weight to the front.
If you go into the woods, you'll need to get a skid plate. A lot of sensitive stuff is underneath and exposed to danger.
You can buy a skid plate (do a search here on the term BX skid plate) or make one.
Best wishes,
