All models have the same BMS. In fact I think all years have the same BMS.
Leftie is pointing out that some models have a heat pump instead of simple resistance heating. He is probably giving you good advice since he lives in upstate NY, in a climate similar to yours. OTOH heating is a personal preference. I live in Colorado and make do with seat heating, gloves and warm clothes. I never turn on the cabin heating so any possible differences in the heating efficiencies between models does not matter to me. You should also know that heat pumps drop in efficiency to the level of a resistance heater as the ambient temp drops. I don't know the specifics of the heat pump in the LEAF but I would be surprised if it helps much below 30F
The good news for you is that there is little price difference for the higher trims in the used car market.
