Everyone seems to say stepless is just far superior to stepped adjustments for dialling espresso.

But as a beginner coming from instant coffee, am I really going to notice any issues dialling in with stepped adjustments? Would even someone with more experience encounter issues much with most stepped espresso grinders?

I'm thinking that the difference in espresso I could achieve with each might be negligible, while the convenience of being able to easily remember and return to different settings for going between espresso and pour over, or two different beans, would be really nice.

Am I underestimating the difference in flavour if you can't dial in quite right? Is it something I wouldn't notice as a beginner but might down the line, or would it never be a massive difference?

I'm specifically looking at the Turin/Itop SD40 vs SK40. I've also considered the opus, but ruled out the Encore ESP (aesthetics and build matter to me)
