The remix is better than the album version by a ridiculous margin. I haven't read a lot of the comments in this thread, but would not surprise me if older pure "rawk" fans don't like this version because it is more hip hop/R&B in tone. That's not a criticism of them just an observation, I wouldn't like GNR Dubstep, everybody has their box they are in musically.
Vocals are better, the overall structure of the song is better, it's catchier. I get people are attached to Robin's solo, but it would be out of place ham fisted into this version which I think is a funny observation because CD as an album seemed to be Axl trying to hamfist a decade worth of parts and overdubs into each song. This version is more cohesive.
This I Love was not an A level GNR song for me. I don't like the lyrics, vocals, or the arrangements all that much, but this remix version saves it for me. It's very good.
