The bear totem has been completely blown out of proportion as has the berserker exhaustion.
This. I did some math, and the bear's expanded resistance is worse than the Tough feat, worse than Second Wind, in a typical game with the recommended number of encounters and rests. It's still quite a good third-level ability, but it's one of those that reads better than it plays. Frenzy is the opposite. I think the third-level wolf totem ability is strongest choice with the right party makeup, but it doesn't get the same hype. Berserker is better at 6th and 10th, at least when the focus is on the barbarian's combat role, and on equal footing at 14th.
In my house rules, I dropped exhaustion and imposed the cost of an extra Rage on Frenzy, but that was mostly to address perception and to create incentives to go deeper into the barbarian class for more Rages/day. Of course, no one's played a barbarian since I did that, so I can't really evaluate it. In any case, I don't think it was strictly necessary and the subclass is fine as is. If most players prefer the extra damage-mitigation from bear totem, I don't think that's a problem. They can pick up PAM to get that bonus action attack, the berserker can pick up Tough if they want to be, er, tougher. It's all good.
