its not a good versus bad issue, but rather a likely versus unlikely application (and subseqent greater good for those likely needs)
At least until recently... reef aquariums we rather nutrient poor and with few folks actually target feeding corals on a weekly let alone daily basis. For this reason and more, particulate waste of any kind was rather sparse in typical ef aquaria. But dissolved organics would accumulate and concentrate. Thus... we sought to collect more of the drier/darker skimmate to export these finer ordissolved compounds.
But wet skimmate will pull out particulate matter before it gets a chance to degard into excessive dissolved organics. Thus, for tanks especially with heavily fed fishes/corals... wet skimming is better.
In some ways, this issue is like lighting. You cannot say what is good or better for lights or skimmate until you first address the needs of the creatures being kept.
