@loji @gunpla One of my first kits was the Barbatos Lupus, so I can recommend it pretty easily. The Lupus Rex has some color accuracy issues to work through, and I personally don't like the proportions of the base HG Barbatos.

The only joint that tends to be a bit loose in my experience is the one connecting the torso to the waist, and that is pretty easy to tighten up with super glue or purpose-made tools. There's also a spot in the middle of the torso that holds better with a bit of glue.
