Dispell some myths...
I'm recent hire with UPS, and, yes, there is alot of night flying, but there is still daytime flying. In my seat, I can hold a day rsv shift (11 am to midnight). Even the night shift is not bad. In my a/c, most trips are 1 leg into a sort, sit 3-4 hours, then 1 leg back to where you started; almost all legs are 1:30 long and under. It is not a bad gig. Granted, there are other fleets that will work you to the bone every night if you are junior.
I flew single-pilot night freight for US Check and while that was fun flying, it kicked my butt. Those hours were so much harsher than these hours. I feel fine on my off days, and the only times that I have felt tired when getting home were because of my own choosing (i.e. commuting home after working at night). Otherwise, it is not bad at all.
The biggest thing that you should consider is the stability of cargo vs. pax. Many posters have already touched upon those issues, so I will not rehash. But I think the best advice that was given already is that, you, and only you can decide what is best for you. The rest of this is just mental gymnastics.
Good luck to you and congrats for being in a position to choose to work for 2 fine companies!
