Pros
They're a progressive company if you're in one of the regions that is experiencing growth. They're open minded. If Walmart is the worst of retail, Kroger Marketplaces are the best of retail. Extensive and well paid for training (again, if in the proper regions).
Cons
You really need to be working at one of the Kroger Marketplaces to understand how well Kroger will shine ten years from now. If you're living in a place with slow economic growth relative to the national economic recovery averages and you're not working at a Marketplace .. if those are both checks for you .. then you may not see how Kroger is any better than any other retail company. This is both Kroger's strength & weakness - they're willingness to experiment and innovate - for those left behind it's not so great, but for those able to get in on the cutting edge .. it's better than any other retail experience one could have. Are there cases where I'm wrong? Have I seen people fired improperly? Perhaps. But for the most part - everyone at a Kroger Marketplace actually enjoys being there. There are always ups and downs. I would argue most people who don't get the hours they want are not getting them because of availability or a lack of arguing for them.
