I'd say you'd probably like Infernal Affairs better if it wasn't for your aversion to Asian cinema (but I guess that only applies to arthouse-type films & not the hard-edged HK gangster flicks, so maybe you'd give it a look)

I think it helps add some appreciation to the movie if you're familiar with the Whitey Bulger/John Connelly connection too (the real-life Frank Costello & Colin Sullivan)

the soundtrack also added alot to the movie I thought... but I'm guessing you're not a big Dropkick Murphys fan either - LOL.
