I know you come from a software company, but if your role is far away from the product side of business, Sloan might be better because I've heard that people from Sloan with no tech/technical background can get PM offers because Sloan is on the target company of many tech firms. But if you have a strong tech background and did coding or strategy/biz dev/marketing on the product side, you should get interviews even without Sloan's brand name.
It also depends on the company you're looking to get into. Some firms do care about MBA pedigree to some extent, but as far as I know, the small (startups) to mid-sized (Adobe/Autodesk) don't really care.
I think if you didn't come from tech and wanted to do PM in a tech firm, Sloan is a no-brainer. But in your situation, I highly recommend talking to people from Anderson with your background (make sure they're not a boneheaded homer who shamelessly promotes their school) and learn from their experience. It could save you a lot of money you could be spending elsewhere and yield similar results. I've had friends from non top 10 schools get into major brand names in great positions because their background matches.
With that said, if you're open to recruiting for other fields and/or moving away from the west coast, I think going to Sloan would give you more options.
