I'm familiar with both Centipede and Bermuda Grass. I live north of u (upstate SC).
About 8 yrs ago i sodded my yard with Centipede. I can say truthfully that i have no regrets.We have been thru about 4 years of drought (as u well know) and my centipede looks fabulous (that's with very little fertilizer and very little lime -i haven't really bothered with either because it was so hot and dry). It's a true warrior when it comes to drought. I don't have a sprinkler system and i never water it. It can be brown one day;rain, and be green the next- not kidding! Centipede is considered a very "maintenance-free" turf grass. Bermuda is considered a "high maintenance" turf (it does look good though).
The 1st few years i hooked a pump up at the creek and kept my yard watered. That was a mistake. I made it so delicious that the insects were thriving! i finally stopped that and let nature take it's course. By letting the grass turn brown a few times, the spit bugs didn't have a chance. That's the way it is with most all grasses.
The only serious threat i have experienced with my yard has been the June Beetle grubs. When i saw them flying around by the hundreds one day, i knew they had infested my turf.They weren't killing my grass but i knew with the drought, my grass wasn't 100%.
The bottom line is this---Bermuda is a very attractive turf, but requires more maintenace than centipede (fertilizing and liming several times a season). Centipede, is not as showy (still looks very good as long as u keep it mowed), very drought resistent, good in shade, and requires little or no fertilizer.
