Selecting a modular helmet....

Hi everyone, I stepped in to ask your folks opinion on these 2 helmets.
As you understand, I need to pick only 1, and both seem to be good enough.
Shark Discovery EvoLine Series 3 Hakka Modular Helmet at Moto ID
Nolan N100-5 Motorcycle Helmet Black Graphite on Amazon
I tried both, and both fit shape of my head, so it's hard for me to select one. That's why before I go and spend $400, I'd like to ask you to kindly comment on helmets by these 2 brands.
If you have experience with 1 of them, please let me know, what you think.
Thank you!
Either one is good if it fits well.

I have been using Nolan 104 EVO for the past three years and it still is snug after 15,000 miles + of riding.

The Shark is good if you want a helmet that feels and protects like a 3/4 helmet.
