My vote would be the Class 2 job without a doubt.
I’ve done 7.5T work with 40-60 drops a day, can’t express my true feelings about that as the zb filter would be working overtime. I agree the commute will grind you down, but personally the 40 drops per day (and the rest, because I’ll guarantee that’s a minimum rather than a maximum) would be a bigger grind in my opinion.
