You do mean LTX M/S2's ? Of those two I'd go with the BFG's. It's not really a fair comparison since the BFG is an all-terrain tire and the LTX2 is a highway all-season tire. My Cherokee XJ came with the original LTX's. They didn't work out for me at all. Also this from the Tire Rack site:
The LTX M/S2 Highway All-Season tire is NOT a dedicated winter / snow tire. It does NOT meet the severe snow traction requirements and is NOT branded with the three-peak mountain/snowflake symbol (3PMSF).
