Bruno is easily the most talented pop artist at the moment in terms of pure live performance.
I would go to a Bruno Mars concert. I would not go to another Weeknd concert.
Weeknd struggles live and doesn't put on a great show.
However, Weeknd released better original music while Bruno Mars is literally just copying artists he likes and re-arranging the melodies. Nothing Bruno Mars does is original.
If we're talking about pure sound then The Weeknd probably sounds more like MJ, though he can't push his vocals that much. Bruno can push far more.
The Weeknd's most 'MJ' song: I Feel it Coming
Bruno's most 'MJ' song: Versace on the Floor (? maybe - the beginning really reminds me of him)
Uh...Neither
Can't stand the weeknds falsetto and Bruno Mars is such a niche artist.
They both have never shown the ability to genre switch or much creativity within their lane.
Eh? Bruno Mars seems to change genre every album - he's on the funk train at the moment. Again, he just copies artists he likes though. Nothing original.
50's haircut to 60's "doo wop" and James Brown dance moves to 70s disco (treasure) to 70s funk (uptown funk) to 80s pop R&B (24k Magic) to 90s R&B
