I am working with the Shoie Rf1400, it was on your list but in Ducati graphics. To date it is probably my favorite helmet ever owned. I intended on moving back to Arai but after 10 years they feel cheap to me. The intake venting mechanisms have not changed since my first Arai back in the late nineteen hundreds. How could this be? Have there been no advances on 20 years? Or do they feel they just got it right the first time? Some will say to get what fits you best and this is true to a point. Most premium helmets are customizable to make the fit perfect. Shoie, you can buy each pad in 3 sizes. Arai, their padding is a leaflet style. You can take some out or put some in to make it fit perfect. This is just my .02$. also, Schuberth have always felt cheap to me, especially the modular. I wanted to like those helmets so bad but they aren't for me.
