Depends on your career aspirations and goals, and where you want to or are willing to live.

Good corporate gigs are often hard to come by, and although you will make less money than at UPS (especially with the new TA) your quality of life will probably be infinately better in the corporate gig...unless you are willing to move in domicile and bid reserve. I know many Part 91 guys making far less than top CA pay at SWA/FedEx that wouldn't fly 121 if their lives depended on it. That being said, often the first thing to go in hard financial times is the corporate flight department, so study its financials hard and realize once you have a solid corporate background, its much easier to go to bigger/better corporate departments making substantially more $$$.

This is a good problem to have - good luck with your decision!
