I didn't really realize that it was splitty cause it was one of the first yarns I ever worked with, but looking back I think it is a bit more splitty than other worsted weight I've worked with. Red Heart is less splitty but it just feels gross to me, I prefer the Caron anyway. And I've used Plymouth Encore, which is a lot less splitty, but not as soft though it doesn't hurt my fingers like Red Heart (I haven't washed it yet, though, and I've heard it washes up nice.) Caron One Pound is not as soft as CSS, but it's less splitty.
That's basically all of my adventures with cheaper worsted weights, hope it helps.
