i never said that you couldn't have high pressure, high power setups with an internal, but the ability to hold boost better with an external setup, boost control, and reliability is a lot better compared to an internal. plus, if anything goes wrong with the external wastegate, it is tons easier to tinker with it than if you have an internal setup where you would have to take the turbo out which would require you to unhook all of the lines going to and from. plus if the internal wg somehow gets messed up, it could end up being a costly repair whereas the external gate you would just have to get a new one or call the company and get the specific part that you need.
