I think the answer is they jumped all in and they are fully incorporating it into their workflow. If you’re not, like I am, you have a different experience and that is obvious of course. But objectively you probably are right about mild improvements as I feel the same. But I can’t speak as far as the all in experience. I may be missing overall but usually am set in my ways until something convinces me to reset my ways. LLMs aren’t making the dent though I have to admit I use it at least once a week and am happy with that use alone.
