Once again: RHEL 6 is completely different from Redhat 6.
Same company, same number, but entirely different products.
RHEL version 1 was released in 2002, RHEL 6 was released in November 2011.
Sorry, I was mistaken there then.
I've used HFSS on CentOS 5.3. I've used HFSS on CentOS 4.7 with no issues at all (works just installing from the DVD). I've also used it on CentOS 5.6, but that takes a bit more work I think. I believe I needed to install a library which was not on the DVD
CentOS is said to be 100% binary compatible with RHEL, as it's derrived form the same sources. But the name Redhat is removed in most cases. I did find it necessary to edit /etc/redhat-release to install HFSS. One just needs to change the name and version from CentOS to Redhat.
CentOS is free, which is nice!

I would agree with you that Solaris is excellent too (in fact I used to prefer it, at least for a developer it is
trailblazing), but for desktop use it is hard to use, due to lack of (for example) wifi drivers, and these are
a showstopper for most people. For server use, Linux can be as reliable, and some people have an aversion to Oracle (not always justified, but not always unjustified either! ; ).
Yes, Solaris is not too good for desktop use, though I do use it myself, but then I have a Sun Ultra 27 workstation, with all Sun hardware, so its not an issue.
I'm a bit less keen since Oracle bought Sun. Since the takeover, the source code has been closed, after Sun opened it a few years before the takeover.
I used to go to the London OpenSolaris User Group (LOSUG) meetings, which were always interesting, with free hot and cold food and alcohol. Since the takeover by Oracle, there is no hot food or alcohol, though there is cold food and non-alcoholic drinks.
