Since 8.1.5 is out, I would recommend reading the release notes to see what has been resolved as far as bugs as well as vulnerabilities. Also it lists any known issues that have yet to be resolved. I would also recommned putting which ever version you are going to run into a dev/test environment to see how it behaves on your network.
Unless you need the features released in 8.1, my continued recommendation would be that you don't install it unless you have a suitable test/dev network to properly test this in your environment prior to install.
If you need the features available only in 8.1, then you should be utilizing the current recommendation of 8.1.4 to continue to follow best practice. That being said, with 8.1 I actually would feel safe in recommending you install 8.1.5 at this point, but I don't know if TAC is officially recommending it just yet.
