Unfortunately price is still a huge factor for me. I'm having enough difficulty trying to justify $100 for a grinder.
Yeah it's different for everyone, really depending on the vapes you're using it with, but also remember how the grind is so dependent on the herbs themselves. For me a lot of times if I'm getting a fine or coarse grind is dependent on the moisture level of the buds I'm using at the time... Remember there is a course and someone here even did an extra course custom, so I think it is fair to choose medium if you only want to get one plate. My plan was to only get one BCG with one plate and I went with fine, I was glad because it didn't grind super fine on its own, to do that I had to turn it upside down, all around a better experience than any other grinder I've used and will be great with the big one I'm sure! Anyway a year later I got another BCG with a medium plate, and I do like having the option for the more course grind... So if and when I get the large one for myself, I think I might get the medium honestly... Also it is a larger grinder overall, so that could affect things, I don't know I could see making a case for getting the fine, it depends what vapes you're using what kind of consistency your herb is and how you like to load it, etc... I think you won't go wrong regardless of which one you choose honestly, it will be pretty versatile, you can control it by how you load it and how you then grind it yourself (large nug small nugs upside down how many turns)
