having both (one of my PC's still has it on the taskbar) I can tell you that the one on the taskbar provides better, more succinct responses. The "app" one leads to more "story" like responses with many links to videos. the Taskbar one gets to the point. Further, in my experience, the app one has an annoying tendency to provide the same answer over and over where as the taskbar one tries different solutions. Today, I was laboring with a custom column that kept erroring when attempting to do math (a different multiplier based on the Unit of measure). I tried at least 4 answers from the app, none of which worked. One was a suggestion to return the word "error" on an error. Out of desperation, I remoted into my windows 11 PC that still had the Taskbar version and it found the error with my formula first time and provided a solution. (there were null values in the number field).
I've tried all manner of regedit's to get it back on my taskbar with no success :(
one more petty point, the taskbar version respects my theme (Dark), the app keeps eye searing white. :|
