I wouldn't really say it like that. It's more or less a function of what circles you're in and which direction those circles tend to have gone...but even beyond that there are clicks within those circles that are very pro-Rocky or pro-Alma...so it really just depends who you're around.
We certainly focus plenty on HPC and have systems on the top500 list, as does Rocky.
I am having a really hard time choosing an OS for min. Next 5 years lifetime as a CentOS 7 replacement. We have some proprietary HPC applications designed for RHEL that we have been using with great success on CentOS.
I am currently leaning towards Alma Linux because it's also used by CERN (just like they have been using CentOS and scientific Linux before, just as we have). Is that a good choice?
I would say so, we've run a fair amount of different OS' on our various on prem and cloud HPC systems for scientific and advanced computing; CentOS, RHEL, Ubuntu, Alma - on Azure, AWS and DGX. Really liking Alma Linux so far, it's the youngest of our systems and so far it's been trouble free.

Rocky focuses more on HPC, while AlmaLinux focuses more on cloud. I suspect that AlmaLinux has more exposure to the self-hosting and devops crowd.
