Crib mattress? Newton worth the hype?

So im looking into crib mattresses. I heard of the Newton breathable mattress but its quite expensive!! Especially US to CAD conversation it comes to like 400$.

I have a 100$ gift card from a mattress store and they are selling a Safety 1st crib mattress that seems to be good for 170$ which is a lot more affordable!

What do you guys think? Should I splurge and get the Newton or stick to the Safety 1st?
