I spent all mu Christmas wishes, but my birthday is soon after

One of the Gath helmets is on the list for sure, but...which one?
I would like my eyes shaded, and my face protected from the sun.
So a beak or a visor is a must.
If the guys using them could tell their experience?
The beak may not protect from the sun too well.
The visors scratch. Do they get foggy?
Would they obscure the visibility? Are they polarised?
Full face or small visor?
