You are right... I grew up with 2ish acres of grass to cut and it fell to my brother and I. Took around 3.5 hours with trimming etc. There is a cost vs speed calculation to be done here. I also grew up in an era where before my brother and I could mow, my Mom was home full time so my overworked executive Dad only had to mow a few times per season. Depending on OP's situation (kid age, wife ability with a mower) 2-3 hours a week in cutting lawn is a big commitment. With my young kids right now, I would be looking for the fastest mow ability I could find. If they were a little older, it would be a different discusssion for sure.
We went the ATV and plow route at home (in addition to our CUT) and later at the cottage and it was great... until the snow gets high (which in Muskoka was 10 mins into the snow season). We had a fully paved driveway at home so it would be very clean.
