within you’re choice of three theres not a huge amount of meaningful difference. An impact driver makes up for any torque shortfalls any of the drills might have.
I don’t know if I’d choose a metal gear box / housing on a drill driver again. Notionally they’re tougher but they’re spinning more weight and bringing it to a dead stop each time you use it and I got much less use out of my old metal geared MXTs than the cheaper spec LXT I replaced them with.
I bought the low end plastic housing LXTs on a propotional deal as a way of switching up to Li-ion batteries when they first came out. I expected I’d end up replacing the drill bodies pretty promptly but 7 years later they’re still going strong and I only used to get 2 or 3 years out of the MXTs for the gears would start slipping
Unless you have very roughty toughty work planed I’d choose the lightest option. If you can get a cheaper deal on the same bodies with 3 or 4 amp hr batteries go for that, no real benefit in paying for higher capacities when you’re working around the house.
