Apple today seeded the fourth beta of an upcoming macOS Mojave 10.14.3 update to developers and public beta testers, a few days after releasing the third beta and more than a month after the launch of macOS Mojave 10.14.2.
The new macOS Mojave 10.14.3 beta can be downloaded through the Software Update mechanism in System Preferences after the proper profile has been installed from Apple's Developer Center or the public beta testing site.

We don't yet know what improvements the next update to macOS Mojave will bring, but it is likely to include bug fixes and performance improvements for issues that weren't able to be addressed in the macOS 10.14.2 update.
No new features were found in the first three betas of macOS 10.14.3, but if we find anything new in the fourth beta, we'll update this post.

I have no doubt it will be 'rock solid' for almost everyone. The issue is, when the time comes you want to replace or upgrade the storage drive in any of the T2 chip equipped macs, you can pretty much forget about it and just get a new motherboard or replace the computer entirely.
I fix Macs as a hobby. And I can't tell you how many Macs I've got running again for several years just but swapping out the faulty storage drive (ssd or hdd).
That will no longer be possible with 'T' chip equipped Macs, which is disappointing to say the least.
Perhaps they should’ve kept Tx functionality limited to TouchID like with the T1 in the 2016-2017 MacBook Pros but what can we do. It’s just not up to us.
While I think FaceID would be great to unlock the computer, I still think TouchID is the better solution for passwords and Apple Pay.
Since FaceID is instant, it doesn’t give you time to cancel or change your mind when making a purchase or modifying protected system files for example.
As for Mojave, it’s been rock solid for me as well on 2016 15” MacBook Pro. Honestly every OS I’ve had on this machine has been fine with the exception of the first couple of High Sierra releases and even then it was more of an annoyance with some error messages in the console like “month 13.”
My 2018 mini has the T2 chip as well, but I have had no issues with it using Mojave.
As for Mojave, it has been rock solid on both my personal minis as well as my work mac pro 2012 and macbook air 2014.
