Sanesh, there is a fairly accepted logic that - ridden hard in our locale - all single crown forks will _eventually_ develop creaking pressfit interfaces. A lot has changed since 2010 that conspires against CSUs. First off, the riding that the average person is doing on a single crown bike these days has progressed massively (speed and ruggedness). Headangles are much, much slacker, and larger wheels have an effect as well. Plus, stiffness has gone up-up-up: carbon wheels, stiffer frames, shorter stems, stiffer bars, etc. There are two proven ways that some brands have eliminated (or at least very consistently reduced) issues with creaking CSUs at least within a more reasonable time frame. One is adding a tonne of material - more steerer overlap, beefier crowns, thicker stanchions. A couple or a few hundred extra grams in a CSU and even Brett Tippie can get a season out of a fork without creaking (and sell it on with a clear conscience). But at their heart, pretty much all mountain bikers are weight-weenies and suspension brands are all aware of this. The other way is QC/QA engineering - making certain the interfaces are perfectly toleranced and using products to prevent any future corrosion of interfaces. This will add to a price of a product and with the exception of truly boutique objects (like that [**EXT ERA**](https://nsmb.com/articles/ext-releases-era-fork/) fork AJ wrote up) most companies recognize there's a certain price point range they need to hit with their top-end forks. Not that they haven't had other, well documented, issues but Ohlins is an excellent example of a brand that seems to have sorted out creaking single crown CSUs for the most part. I also have communicated with a fair number of riders on the Manitou Mezzer and none of us have had a creaking CSU to date - the fork does have generous stanchion and steerer overlap. \-\-\- TL/DR: There are a lot of different good fork options on the market today both on a budget and at the top end that are less likely to develop creaking than others (or at least are more likely to run creak-free for longer). \-\-\-\- There's certainly an argument to be made though that instead of the Fox 38 and the Zeb that Fox & Shox could have (should have?) focussed their energies on making lightweight dual crown editions of the 36 and Lyrik. Both brands probably have a lot of consumer data to back up sticking with single crown forks (for one, DC forks are a lot more expensive to produce) for the Enduro market.
