Most recent, yes, most modern? I doubt it.

As for good looking, I'd still put the Merkava (all 4 models) at the top of my looks list. They look almost Sci-Fi futuristic... like you could delete the tracks, add armored skirts, and it'd be a version of a Frisian-made, iridium-hulled, powergun-armed tank like Alois Hammer put to good use...
