I think it's a question of style. Jeff Buckley's folk song version, with just a voice and guitar, in pretty much a monotone style, is certainly closer to the way Leonard Cohen wrote it.I know you're not fond of Leonard Cohen so I could see you taking her version over his but I don't think it holds a candle to Jeff Buckley's version. To me, Buckley's Hallelujah is one of the three greatest covers in popular music. I'd put it right there with the Jay and the Americans version of Cara Mia and Harry Nilsson's cover of the Badfinger tune Without You.
Whereas Alexandra Burke's version is more of a production number and even gospel when joined by the choir. After all, it is a religious song.
There have been very few cases over the decades where I have preferred a cover over the original. Such as Hall & Oates' "You've Lost That Lovin' Feeling" over the Righteous Brothers' original version. Another example was when Bobby Darin did a big band version of Mack The Knife only a few years after the original jazz version by Satchmo and it became a mega hit. And I enjoyed the Beach Boys' version of Sloop John B even more than the folk song we sang in college.
In this case, I found Alexandra Burke's presentation to be one-of-a-kind and very reminiscent of the way Whitney Houston presented her songs.
To me, Leonard Cohen wrote a great song (of course), but Alexandra presented it in a heart wrenching style. 'Just my opinion. No right or wrong.
