We have no issues running RHEL7 under VMware.
Disclaimer, I happily work for RH and today's blog has me ear-to-ear grinning.

What features are you interested in?
I work for a company that sells software which runs on top of Red Hat/CentOS servers. As a result, sometimes we have to tell our clients that the issue is on the server level and that they need RH to take a look at it, assuming they're paying for Red Hat support.
FWIW, I've never heard any of them complain about Red Hat. I've had plenty of them complain to me that I'm sending them to RH instead of fixing their server for them (because that's what software engineers should do, right?), but they've never once complained to me about RH once they reached out.
Many enterprises want up to date and stable software, and since you are paying for stability, why shouldn't you get fairly recent and stable software
Most companies for example don't consider MS SQL 2016 as less stable than MS SQL 2008 or 2012, most users expect the same level of stability from the latest SQL Server than from earlier version, if not more because it's newer and more advanced, might as well be more stable
I didnt use RedHat in a while, so I dont know how bad the situation is , I hope it is not too bad
SQL Server 2016 may be better than SQL Server 2008, but enterprises aren't deploying it until it has baked a few months, and maybe sp1/sp2/some major rollup ships for all the bugs the suckers find at rollout
We've hit more than one kernel regression in staging.
With things like Software Collections and IUS you get to run the latest stuff on a rock-solid base. I don't want to upgrade my kernel to get a newer Python or NodeJS release!
Frankly, having a lot of new companies adopting a mantra of "move fast, break things" makes me want to 'upgrade' less and less. I need stuff working at Monday at 1PM for the weekly test offering not some oops.
1) deep freeze or virtual machines are your friend.
I support both Ubuntu LTS and RHEL in production (multiple releases each) and RHEL has been rock-solid for years while there's constant trouble with Ubuntu.
Documentation is great.
