I've caught the same wild fish multiple times too.
I like that blog, and don't take any issue with what was said in it. Not all of it perfectly lines up with my experiences, or personal opinions, (some does) but hey that's ok. I enjoyed the read.
We all prefer to fish for wild Trout over stocked Trout. Nothing wrong with that. As far as which is easier to fish for...It depends IMO...On a lot of variables that are constantly changing.
In certain conditions, wild Brown Trout are very easy to catch...Try fishing a small to medium freestone that has wild Browns after a mid-Summer Tstorm, with a Black WB. Come back when the water is low, clear, and cold, and you'd swear the stream is completely dead.
Wild Brookies will literally eat anything you toss at them...As long as they don't detect your presence first. With their vision capabilities, and the location of their eyes, they can literally see behind themselves though. You spook that fish first, it won't come back out for a live nightcrawler tossed into the pool.
Stockies IMO are initially very dumb...They think anything that hits the water is food. They've been conditioned to do that. But they figure it out. I've had stockies on Pine or Kettle refuse my dry fly presentation more times than I'd care to admit. When hatch fishing, and it's obvious what bug they're eating, I'd actually bet my take % per drift is higher on wild fish on say Spring, than stockers on Pine or Kettle. Why...I dunno? Pressure maybe, but Spring fish see a lot of drifts too.
Edit: Another example...I find the stocked fish on the lower Tully very difficult to catch, especially on dries. Go upstream into Lebanon County (above the dam), and the small wild fish up there I find fairly easy to catch.
