Difference in feel between gravel tire sizes

now that many gravel bikes allow fairly large tire sizes I’m wondering about the difference in feel between sizes.

I currently have pirelli Cinturato M 700x45 on my bike. They’re okay but they always feel a bit sluggish and I would say they don’t feel particularly supple.

I have some Maxxis ramblers 700x45 120tpi that I might put on but I’m wondering if getting the rambler 700x50 would feel much different than the size 45s.

I don’t worry too much if the ramblers are the fastest but they’re a good all around tire and I ride on a variety of gravel from fairly smooth to chunky to clay and some sand.
