I am an efficient member of my software support team. Our work require us to run various database products and application on various computer. But its support is not at all proper on other RPM. So I would like to have any other distribution which is efficient, smooth and should be an RPM family member because its requirement for other applications. Does anyone of you know the best Linux distribution of red hat family other than centos and red hat ? We have tried centos and it doesn't suit our needs.

I have experimented some of the Linux distributions and here is what I concluded with that:

Debian should be considered as a robust and well-supported distributions that I have came across. It has a great selection of software and dependency isn't bad at all.

Fedora can be used and have a good installer but it is not recommended for general purpose usage.

On the other hand, regarding OpenSUSE, I had seen a binary distribution with a large repositories, user-friendly, easy to install, and great localization. It maintains a strict policy of ensuring all code in the standard installs that will be from Free/Libre/Open-Source Software solutions, including Linux kernel Modules.
