In my experience, the right teapot will bring a little something extra that adds to the experience, but when a teapot makes too big a difference, it tends to be for the worse. And a teapot will not compensate for bad water or make otherwise poor tea good, let alone great. A fine teapot will not save you money by getting good results from so-so leaf ; rather, it will make you spend more money by making your experience with good teas just a bit better.
Though really not being a collector at heart, I have found teapots to be satisfying to look at and manipulate for reasons I will not try to fully explain. There is a reason people tend to collect them. TAD is real. Run away while you still can...
Although it certainly would be nice to save a bit of money on the tea itself, I suppose the ultimate goal is to have the best tea-drinking experience possible. The rabbit hole vibes are pretty strong, though
I have to imagine with an expensive new teapot, particularly if devoted only to a single type of tea, it truly is only a matter of time before one feels the need to find it some friends!
My first kyusu was from Gyokko. Ever since getting my first pots from Hojo, I have stopped using it. Its clay is too muting to my taste (it is a kind of grayish-yellow clay). Every time I have given it a chance, I was reminded why it had fallen out of favor to start with. In addition to that, while it is entirely fine for what it is, it is not as nice to use as the other ones I have gotten since.
After a warning, some enabling
I think my Gyokko is a bit different, and perhaps less porous. Maybe i'll end up throwing some sencha into the Nosaka to compare.... So it begins, i suppose
Here's the Gyokko pot (mine's the one on the right, the 170ml one):
