I suspect you will be happy with any of those. Both brands make good tractors, and the size and HP range you are focused on seem appropriate for the tasks you describe. For me, what sealed the deal is the cost of the factory backhoe bundle. LS was substantially less, out-the-door with frame mounted backhoe, than I could find on any competing tractor.
You might want to look at small details the dealer can demo for you for those models, like ease of mounting/dismounting the backhoe. Probably similar for both brands, but sometimes a small detail can make it more difficult. Or fuel tank position/ease of refueling. It's that kind of stuff that makes daily living with a tractor more or less satisfying.
