One point that stands out is that the company in OK City has been hurting since 9/11 (less business travel means less businessmen renting their "product", if you know what I mean). They had their first ever layoff last year, and IT wasn't spared. The director I met during the daylong interview says that business is coming back, the company has no plans to outsource IT from their world HQ in OK City, and there's lots of Tandem work.
Sore point: their annual report isn't available for viewing on their website.
Company in Columbus has very good financials. Lots of business, actually picked up a new customer (Bank One) that required a whole new Tandem just to handle their transaction load.
Neither one is making noise about non-Tandem exposure or training, so it's up to me.
Primary coin flip result is going to be based upon the city more so than the company itself. That's the tough one so far.
