@mutazoid they say the safest helmet is the one you actually want to wear.
For head, and neck protection, the
Hövding 3 airbag looks pretty amazing. The 800g ring drapes onto shoulders not head. I very nearly chose this one. It may not be everyone's cup of tea as far as aesthetic. Not sure there is any distribution in Canada yet.
If you're riding in low light, being seen easily by other road users (wrapped in steel cages) might a more optimal survival strategy for the whole body. I went that route with a
Beyond Classon but there are others like that with position markers and turn signal lights, right up at driver eye level. Again, maybe not everyone's first aesthetic choice, but I quite like it.
In the realm of traditional skull buckets, the MIPS type are probably the safest and worth splurging for. Some of them have bluetooth connectivity to message a loved one (like OnStar) if you have a big incident. If fashion is your bag, then the
Thousand helmets channel polo-player chic (with a pinch of the Great Gazoo). The
Sahn helmets out of Vangroovy looked neat, but had a huge production recall, and I'm not sure they are still around.
The best choice for you will consider 1. which one you think you'll actually want to wear, 2. where, when, and how you ride. One day all of this stuff will be integrated into one device, but for now, it's a choice and a compromise.
