On ext worked a lot of professionals.
Since s2Ext is a spare time project, too, there are
by definition no professionals working on it.
And what he said is: You could spare some work, if you would only merge some things into your mod that others have already done (trading system, coins, chest, saw, sulfur, saltpeter, gunpowder...). But I guess you've already done most of it on your own anyway - by now.
He was not at all comparing the mods.
