With a needle size of 8 it's probably a worsted weight so yes, it's comparable weight to RHSS.
I personally think it probably is softer, but some people like RHSS and think once it softens in the wash its fine. My only point here is that because we all have a different tolerance level it's a tough question to answer.
They always seem to have it in stores like Michaels, Hobby Lobby and Joann. I haven't been to one in years, but they used to. Is there any chance you can check it out first?
