I use a new Stilo along with an Arai GP5W. I've worn Arai motorcycle helmets for a long time and trust both brands.
Stilo doesn't give up much to Arai in quality, both are certainly a level above upper end Simpsons and Bells. I had an order for a new GP6 but couldn't wait any longer, Arai had some delivery problems last year.
I got the Stilo because of the available options and add-ons, this one has integrated earmuffs, water hook-up, carbon peak visor for hot events that allow them, and top-mounted air blower inlet attachment. The Arai is set up with custom earbuds and IMSA plugs, works great but not as clean when I'm not using comm.
The water hook-up is handy in Texas for enduros and junkcar racing. However, I love the superwide eyeport of the Arai, just lets in a lot of air if you run visor up.
I wear XL in both, fitment is very close. I have a round head profile, the Stilo is slightly tigher in the forehead, but it has a removable top pad and both have adjustable cheek pads.
