It's a tough contest, this one.
All of the 4-Series' rivals offer more style, but the 4-Series stands alone on being available as a folding metal hardtop convertible and a 5-door hatchback (curiously marketed as the Gran Coupe).
The Mercedes-Benz C-Class coupe is one of the segment's freshest and it balances the C sedan's swoopiness with a little more flavor inside and out.
The Audi A5 is new for 2017 and it remains conservative but hugely desirable as either a coupe or a convertible—or even the S5 performance variants.
From Japan, the Infiniti Q60 and Lexus RC offer more dedicated takes on the two-door recipe; they're not quite sedans with a different profile, and that's admirable.
