I lived near downtown Gulfport and it was a ~35 minute drive to Diamondhead, so if you worked in or around downtown and lived in Diamondhead that's an annoying drive. Hwy 49 near Creosote gets really congested around the 9 and 5 times too, so that's also something to consider.
As far as the hood goes, I lived on the beach on the other side of the railroad tracks from what was considered the hood and there was never an issue, before or after Katrina. The coast's crime rate is below average, and I don't think that's lost on just one town. If anything I'd consider the shanties near the casinos in Biloxi the only really rough part. I'll never forget a time in high school when we were leaving the mall and we witnessed something Asian gang related where a guy drove up and got out of his car and shot a gun in the air twice before flooring it off in his little rice rocket. If you're not in an Asian gang I don't think anyone has anything to worry about really.
There are a lot nicer neighborhoods right off Lorraine Rd in city limits than anything in Diamondhead, Pascagoula, or anywhere otherwise. The owner of Killer Bee bait has a house in that area modeled after the White House, and those are the kind of people you're dealing with there. There are several million dollar houses in the area, and the overflow neighborhood is middle-class with several upper middle-class families mixed in. That's why I think Bayou View is the ticket, it's just a really nice neighborhood and I think the property value is only going up considering all the high dollar housing in the area.
I guess it's all a personal opinion, but I believe south Gulfport and Ocean Springs are the nicest places to live on the coast. Downtown Ocean Springs is a thing of beauty, especially if you're fond of the Oxford Square type of thing, but if you're commuting to Gulfport every day it could be a pain. It has the highest average salary in the entire state and I believe it's the only school with an IB program. On the other end GHS is the only school in the state that has replaced textbooks with Nooks. Every kid in the school is given one on the first day. Crazy to think about when you consider that there are schools in the delta using textbooks from 1960.
As far as hurricanes go, it's never been an issue. I've literally witnessed dozens of hurricanes in my short lifetime which has been entirely spent 100 yards away from the Gulf of Mexico. Board up some windows if that's your thing, but you'll be good. If not, every home that came within 100 feet of being wet in Katrina is now required by law to have insurance... so you'll at least get your money back.
