Choose the global or the gulfstream. In terms of cost, they are the highest costing types out there (35K+). Having experience teaching in the sim and or serving as a seat sub would most likely allow you to find a job out there as a First Officer on one of those planes, which is going to mean good pay and most likely a good quality of life while getting to see some incredible places.
Working down, I would rate the Falcon and Hawker types as the next in the line of succession for the same reason, then the Citation followed by the Learjet and Beechjet, because of the number of jobs that there are for people who are typed in those models. The bottom of the list would be the CRJ, the JetStar, Commander and 200/300/400 series simply because either lack of jobs, poor pay, or the fact that everybody out there has a CRJ type rating and the market is saturated.
