Compatible with most oracle products
Unbreakable is really unbreakable but can lose network connectivity
Free patches and updates in oracle repository
Works well with oracleasm and database installs
Free of charge (except for some features)
KVM hangs and downtime
Experienced data loss upon plugging san & external storage
Experienced network packet loss
Incompatibility for some application installs outside oracle
Poor support, they've shown me the door as if they don't care
Too much to deal with oracle haters

Pros: compatible with the Oracle Database products, Cheaper to maintain than redhat Linux, Ksplice, DTrace tools
Cons: plain interface, relatively small selection of software.
Oracle Enterprise Linux was created out of a need for an enterprise-class operating system that would natively and specifically support Oracle software applications like Oracle Database, Oracle Middleware, Oracle OpenStack and Oracle Cloud. It also needed to be binary compatible with Red Hat Linux.
So why would anyone want to use it?
Oracle enterprise Linux has a number of extra features that a Red Hat Network (or CentOS, Scientific) subscription does not provide:
1). Ksplice provides a way of updating the kernel without a server downtime.
2). Dtrace provides a way of dynamically monitoring the performance and potential problems of a server running oracle Linux.
3). Two kernels: OEL ships with a red hat compatible kernel (RHCK) and a custom kernel called the Oracle Unbreakable Enterprise Kernel(UEK).
4). support options. Oracle support network provides paid support that is nearly one fifth the cost of a professional subscription with Red Hat Network. This is because Oracle Support Network charges for support per server rather than per workstation. One sustaining support license lasts indefinitely rather per year and per workstation. Thus a Red Hat subscription that charges per year and per workstation is much more costly than Oracle's sustain and premier subscriptions.
5). Clustered file system
6). Free updates and patches from ol repository.
7). You are actually getting a finished stable product at no charge.
Oracle's default set of applications (GNOME desktop, Libreoffice, firefox and standard text editors and terminal apps)is very good and very stable. The oel repository has a few nice package groups like scientific support and all the standard apps (Libreoffice, Firefox, thunderbird, Cheese, Nautilus, Dracut).

Finally got it installed; attempted to update - NEVER HAPPEN. Not a paying customer, did not get a "CSI" so I guess that means No Updates. So, I say a bye bye to it.
