I always pay attention to what chefs use at high end restaurants during my in person visits or when I watch food videos. I visited a whole bunch of high end restaurants in Tokyo last year including some of the best sushi restaurants where you sit in front of the chef and can check out their knives in very close proximity. Some knives I saw were ok, but nothing impressive per KKF standard...Some of the best food I've ever had was made using the shittiest knives I've ever seen.
I watched a video about Josh Niland's famous Sydney based fish restaurant last year and saw what he used to butcher an entire tuna fish (starts at 47 sec in the link below). I decided that a fancy deba is definitely an overkill for what I do at home...
