Cool Thread!
I get asked about serrated knives often. Do I make them...."not yet". Do I use them "yes". Why?
Well I see all your view points and take them as valid.....however, I do tend to use serrated knives often in my own kitchen.
It's sort of a misnomer that they are not used in professional kitchen too.
AND, yeah,, they take time to sharpen, but when they are, they excel in come tasks that other knives just do not do as well....
........such as:
> Cutting Crusty Bread of course, especially if it's hot!
> Processing tons of tomatoes for making big batches of salsa!
> Taking the hard skin off a butternut, or any other hard squash when processing it this way as raw to be steamed or baked where you do not want the skin....
...the ability to employ the sawing motion gives way more accuracy and is safer than a plain edge.
> Shredding tons of cabbage when making batches of sauerkraut or creating coleslaw for 120-people !!!....which I just did recently
....Again, with a very sharp serrated knife, the ability to use sort of a 'sawing-pull-cut' that, with dexterity & skill, works far better than almost any plain edge knife for creating ultra-thin shreds of cabbage.
> Taking the zest of citrus fruits.
...I prefer to hand cut the zest than to use a zester in almost any baking or cooking recipe I tend to create....unless I want the zest more open and pasty.
......A serrated knife is again, more nimble and accurate because you can use all those gaps and changing geometry to your advantage and for control.
NOW....
Of course, one can always cultivate the skills with any knife! Serrated of not.
Ultimately I think this is the thing that is overlooked about why kitchen knives are so misunderstood.....because they are so varied!
There are so many different styles from different time periods in history, configurations and construction styles, blade geometries, steels, the list could go on for a LONG-TIME, and in the end....
.......it all boils down to personal preference.
Some like large knives as daily users, some like medium, many like small knives.
Some do detail-cuts, and are into cuisine and culinary art...
Some just need to get that food on the stove, in the oven or in the salad bowl to feed the family.
I own a really cool serrated French knife in my block at home, rarely use that particular knife over the two other serrated knives in my block, but do use it at times and am super glad I have it when I do!
The other two are both bread style knives, one hollow-ground, (this one my zesting machine) the other older Henckels is what I daily open and skin avocados with, & do other things mentioned above and more.
When just out of culinary school, I worked in a kitchen where we had a new employee arrive to be the cold kitchen chef (Garde-Manger) who truly impressed me
with what her main knife choice was, a curved Forschner Bread knife! I saw that lady do everything with it, sharpening it in s steel often and tear-it up....no pun intended

She came to our kitchen from hotel Bel-Air, so no slouch either!

To me, this is the really fun part about making kitchen knives, studying them (and believe me, there is a whole world of kitchen knives out there that is always yet to be discovered)
and sharing ideas about them with others.
Anyhow, i think the motto here is use what pleases you!
And...Enjoy cooking!
Blessings of Health and Wellness You All !!!

All well-used but still going strong.
I even bought a back-up of the Henckels that is spanking new despite being over 30-years old...but so was this one when I got it about 8-years ago.
