Diffusion filter recommandation

Hi everyone, i've been shooting for a while with a soft difusion filter that was very cheap, and I lately wanted to upgrade it.

Obviously there is a lot of different choice, different intensities, and I wanted tthe community's opinion.

I'm into screwed filters. I have differents Hoya filters wich seems pretty good to me. They do the Mist N°05 and N°1 but what are your recommandation and why ?

Thanks for the feed back !
