I voted "Other" for the Hyenas. They are really amazing and facinating animals, and while the TLK characters don't physically resemble actual hyenas too terribly much there is a hella lot Disney did beautifully in TLK in regards to them.
I love that their designs are adept at reflecting two very different modes, goofy and scary, with just slight re-emphasis of elements in their designs. And they rocked some very subtle and accurate mannerisms/behaviors of the animals--not that Disney didn't with the lions, too, but it's more of a focal point when it comes up with the lions when they do, whereas with the hyenas, you consistently get these great little understated nods to greater naturalism than and can see the shadow of real spotted hyenas behind them much more than the lion characters. And as for unique designs, there are a few nameless ones with identifying design tweeks that don't even serve a narrative purpose like the unique Outlanders, other than as background threatening loafers & lackeys.
It's all a matter of preference, though, really, because even choosing between Pridelander & Outlander lions, I would choose the Pridelanders, the uniqueness so many love about the Outlanders I see as a larger creative departure from the original aesthetic/designs of TLK.
