I find it slightly embarrassing that the knife I find the most useful is one of those never-needs-sharpening varieties with a big old plastic handle. But, honestly, I have been in many kitchens stocked with incredible knife sets lacking a single decent serrated knife! I use it on bread, of course, but also for quite a few other foods.
This knife was a hand down from my parents many years ago and as I've replaced everything else from the set, this handy serrated knife has remained in my collection. I use it to cut tomatoes, sandwich wraps, biscotti, and just about anything else that needs a sharp and gentle slice.
And it truly never needs sharpening. I suppose I will eventually replace it with a prettier version, but I will surely never be without a serrated knife in my kitchen.

I use a Sabatier bread knife too and like you, I love it. However, I don't feel as enthusiastic about all the other knives that came in the set I bought almost 20 years ago. After doing some research, I came to the conclusion that not all Sabatier knives are equally good.
Nice. I'm partial to a serrated tomato knife I bought at Sur La Table years ago, even though I have other, "nicer," knives.
