If you're considering buying LR6, don't hesitate. Adobe could discontinue it at any time. They have said that it's their last stand-alone LR....
Actually they've said exactly the opposite.
Adobe spokespersons on their forums have stated that LR6 will continue to be supported and updated for a while longer
and that eventually there will be a Lightroom 7. Beyond that, who knows. But since full, new versions of LR seem to roll out every 2 to 3 years, LR6 was introduced in April 2015 (so is due for replacement within the next year, if they stick with the same schedule), and LR7 should be good for 2 to 3 years after that... taking us to 2019 or 2020.
Lightroom 6 and Lightroom CC are essentially the same thing. If you download the 30-day trial directly from Adobe's website, then decide to buy it... you can license it either way, as a CC subscription or as a stand-alone.
The difference between LR CC and LR6 comes later, with periodic updates. LR CC gets them faster and has had a few relatively minor new features incorporated that aren't yet in LR6 (but probably will be, eventually).
LR6 has been kept up to date (unlike Photoshop CS6, which Adobe stopped supporting a couple years ago). LR6 can handle even the most recently released cameras, so no problem with a D800 that's a few years old now. It's actually Adobe Camera Raw, within LR6, that's been updated (and is shared between Photoshop, LR and Elements... though it's a module that's updated separately with PS, and is built into LR6 and Elements in such a way that both of them need the entire program be updated).
Since you have LR5, you can save quite a bit buying directly from Adobe. There's an "Upgrade" price available during the checkout process there. AFAIK, this is the first time they've ever offered an Upgrade of LR and hey made it really hard to find... hidden in a little pull-down menu in the "shopping cart", after you've already committed to buying, but before you make your payment. Anyone with LR5 can get LR6 (or CC) for under $100 that way. Otherwise, the full version is something like $142.
If you instead subscribe... on the one hand you also get Photoshop CC in the package, along with LR CC. But on the other hand if you let the subscription expire for any reason, LR CC will only partially work. As of now you can access the Library mode (as well as Print and Web modules, which are less useful). But you'll no longer be able to edit your images or Export them from LR CC. Eventually I wouldn't be surprised if Adobe stops the Library module too. Your original files will remain (since they are never truly "in" LR anyway). Any files you've exported will be fine, too. In other words, if you stop payin', the subscription software pretty much stops workin'.
