I have a 2017 Santa Cruz Bronson (160mm front/150mm rear) and a 2017 chromag stylus with 2.6" rubber and a 160mm fork. So pretty comparable set of bikes, both considered pretty top shelf options as far as shore riding goes.
I live on the shore and ride all over the lower mainland on both bikes, but I ride Seymour the most. I love the chromag for what it is, I ride it lots - what bike I pick really just depends on how I'm feeling and what I'm riding.
On fast flow trails there's no real difference. On slow tech trails there's also not much difference. On fast trails with chunk or lots of small drops like John deer or severed, the chromag is a handful and the Bronson makes mincemeat out of them. At least at my skill level. Obviously John deer is a simple trail and you could ride anything down it, but I can pretty much let go of the brakes and smash it on the Bronson. On the chromag I am just doing what I can to stay on the pedals. I feel little need to bring the Bronson to fromme, chromag is great, but I simply don't have the skill or risk tolerance to smash something like ladies at high speed so maybe that's why.
Not sure if that helps. I can say I feel fortunate to have two great bikes. If I could only have one of them... Yikes thats a tough one.
