Absolutely not. The Pivot, in my opinion, has better elasticity. This keeps the boot in the binding slightly better, but it is really close vs the Jester. If you want a safer Pivot, buy the 14 it has full spectrum toe release, the 15 does not. You don't buy either of these bindings for 'safe' you buy them to prevent release. Also, why is everyone here so concerned with 'durability*' of bindings??? It's just not a problem (unless you telemark, then everything breaks). Seriously I handle ski bindings every single day, I see broken brake arms from falls and the occasional pull-out that requires helicoils. I do NOT see broken housings. Ever**. Lastly, about durability, they ALL have an expiration date, they'll become non-indemnified in about 10 years. These are not heirloom items.
(for the record, I own at least 10 pair of Pivot 18 bindings. I love them and prefer not to ski on anything else, but I hate how much flat-out untrue shit gets said about them. It's a 50 year old design, how many 50 year old products are safer than modern designed products? None.)
* If you break alpine ski bindings you really need to question what YOU did to cause it. Don't ski like a meathead.
** Ok, I've seen a few broken housings in the last 25 years, none that inspired a comment like "whoa, why the heck did that happen?" it is always "whoa, what the heck were you doing??" and attached to a ski that looks like starving beavers tried to get to the wood core.
