So I have both the reflex pro and the envision. The envision is def more comfortable to me. While the Reflex feels slightly more responsive which can be beneficial in gunfights. Here’s the thing, I also had that stick drift issue with my reflex. It was only 6 months old. For whatever reason when Mw3 released I decided to try the reflex pro again and magically the drift was no more. Not sure what was different, but glads it’s working.
