Why? Excuse me, but both mentions are wrong. Just read more closely: I don't have anything against each one. They are different and may have a differ effect, depends on goals. Why do you think I have smth. bad relative to your work? Absolutely not. If I will find smth. not working / error or will find a way to improve things, I'll say to you, as usual. It's just normal discussion, if anyone here are opened to talk, isn't it?
