Glass tops pros: reduce evaporation, keep temperature realatively stable, support strip lights easier and keep out smoke and ashes from smokers.
Glass top cons: Get crudy looking, have to remove to get into tank and do trimming, etc.
This is from only my experience.
I'm going to try the best and worst from both worlds with my latest tank 36x18x19 using a small glass cover on the front with about 9" uncovered in the back for mounting my adjustable legs for a Coralife Aqualight. Had the tank built and the top made for it. Will be setting up during the 4th weekend. All my other tanks are covered.
