You sound like you need (RH)EL6, no more problems for the next 7-10 years.
Why would you stick with a 6 months release schedule distro if you don't want problems?
Agreed, unless you need some bleeding edge package, it is better to stick to a long time support release.
It's not a matter of stability vs bleeding edge.
An OpenOffice update that has been out for months is not bleeding edge.
Desktop users shouldn't have to stick with old software to avoid system breaks.
