Don't know. When I grew up in Meridian, it was twice the size of Hattiesburg. Now I understand Hattiesburg is larger. Some of that may be due to city limit expansion (like Montgomery ... it's technically the 2nd largest city in Alabama, and almost as large in the city limits as Birmingham, but in actuality it's the 4th largest, behind both Huntsville and Mobile. Huntsville is the 2nd largest metro) ... not sure. Meridian has two interstate highways that come together there, so it should be in a more desirable location. Meridian looks like a little city, with a few tallish buildings that I don't think Hattiesburg has, but that's only an outward appearance. I'm not sure I've ever been to downtown Hattiesburg so I can't really say ... only been through there on I-59. I went back to my high school reunion in Meridian three or four years ago, drove downtown, and it seemed that just about every business was closed. Didn't see much of the surrounding area so there may or may not be some thriving areas.
