It is always good if you can get used to the sinus hit without them, but I wouldn't discard them. In salt water, they tend not to be needed anyway. Salt water is automatically kinder and more natural feeling up in there anyway. The only time I have used nose plugs in salt water was when I was being asked to do something like alter my approach to bracing, when I was just getting a ton of closely spaced rolling moments until I got it down. There is a point of just having so much water and discharge running out of your nose every time you come up it is annoying.
Fresh water is another matter, and in WW groups you will often see people going thru rapids with nose plugs on. But WW runs tend to organize themselves so that it is reasonable to pop on a set of nose plugs before a given rapid. That's why you will sometimes see them attached to a helmet.
The salt water rush when you capsize in surf was, for me, very distracting at first because the first rush is so strong. But it is still salt water, so it is tolerable if you can hold off thru that initial hit to get your moment to roll.
