You do you, and don't change anything based off what one guy on an internet forum tells you, especially if you're really used to doing it one way and you're really good at it, but that being said, no one really uses or teaches the Weaver stance anymore. Modified isosceles is basically standard now. Particularly because it's useful regardless of what you're doing, pistol, rifle, shotgun, hand to hand, knife fighting, impact weapons, Etc. It also doesn't favor one hand over the other so you can use the same stance for switching shoulders with a rifle or offhand shooting with a pistol, and if you're wearing armor (and you should be) it maximizes front protection without exposing your sides as much.
