While I think Lunala looks more fitting as Cosmog's final evolution stage, I think Solgaleo has had my heart ever since I saw the first trailer of Sun and Moon. I guess it's the idea of a regal lion, noble and proud, shining like the sun, that appeals to me; he's like a grown up mash up of Kimba the White Lion, a Liger Zero from Zoids, and Galeon, the main component of the Brave series super robot GaoGaiGar, which adds bonus points for the massive shout-out factor to two mecha anime series that I absolutely love.
