Without going into too much detail, I actually know more about John Moores and Charlie Noelle from the business side rather than the fan side.
All you have to know is John and Charlie built their fortune and have been in a business partnership for a long time. They are savvy business people who are smart investors because they hire really well. Even though they are no longer involved in the day to day running of JMI Equity and JMI Realty, they are responsible for hiring the team there. The core JMI team dates back to the investment banking group of Alex Brown and Sons in Baltimore. Alex Brown alumni are some of the smartest investors in technology companies (Software). JMI Equity is known as a top-quartile fund (ie their returns on investment are better than 75% of other Private Equity funds).

They make long-term investments and help build out the management teams of their investments. Anyways...John is sure to take some of the same management and business philosophies over to the business side of sports management. He likes to hire data-driven executives who make decisions based on facts rather than the gut (Think Moneyball). Perfect example, arguably the best and at the time one of the youngest GM in Baseball was an intern of the Padres on the PR side, Theo Epstein (
Wiki,

"The way Theo's brain works, he probably could have done whatever he wanted to do," says Kevin Towers, the former longtime Padres GM who was running the club when Epstein started full time in baseball in 1995 as an intern in San Diego's media relations department.

JMI Realty also have a track record of redevelopment and real estate success built around a new stadium.

Personally, I'd rather have an owner who has past success and experience in redeveloping and real estate - if I were a fan of a team that needs a new stadium or upgrade a current one like Everton.
Here's an old article from 1996, a couple of years after the Padres were purchased by John Moores:
http://articles.latimes.com/print/1996-05-26/sports/sp-8722_1_john-moores
"I have a tough time now dragging him away from baseball to consider something that may produce a profit," said Charlie Noell, the Baltimore-based president of John Moores Investments Inc.
"As much as he understands the software industry and has been successful at it, he loves sports."
Said Moores: "My goal is to stabilize the club financially so that it can be competitive on the field and accepted in the community. We're here for the long haul, and it helps that we're using my money and not someone else's.
"We can look at it from a longer viewpoint than someone who's borrowed money from investors, expecting a quick and superior return.
"I'm no great fan of committee operation [such as the 15-partner Werner ownership] for a number of reasons, not the least of which is it doesn't work. I mean, everyone has their own agenda. Some are in it for the fun, some for the investment. There's a dumbing-down effect. All you have to look at is the U.S. Congress. It operates by committee and doesn't work."
What Moores and staff have done in San Diego does seem to work.
...
"He's breathed life into the franchise," acting Commissioner Bud Selig said of Moores, adding that the economics are still a question mark "because there's little margin for error in a small market, but the early dividends of an energetic and aggressive philosophy are paying off."
The cynic will say John Moores left town, made a $400M+ profit and did not stick around. The realist will take everything into context and realize he lost half his money through a personal divorce, and probably would've kept the Padres if his ex-Wife wasn't out to take half his money.
