One big difference is most commercial people get married to one or two buildings for a long time. It is not like residential where you actually get outside now and then.
The guys I knew on the construction end of the business were starting to get cabin fever after about 2 years in the same jungle of steel studs and pipe. Different day, different room or floor but pretty much the same view every day. It can get real noisy too. Bare concrete as far as the eye can see with a couple of steel framer crews whacking studs on a chop saw and the noise will open up your sinuses. I used to carry ear plugs on my inspections and I used them a lot.
I suppose the guys who are in the retail end of the business have more variety than new construction but "maintenance" can still have you married to one building.
I guess it is all what you like.
