It's the only Glorior Belli i've heard and I don't think I've listened to an Immortal album that I didn't like, so in the big picture I wouldn't argue this.
But I really like how they use southern rock riffs very well with black metal. So, for me, they win for being unique (unless some other band has done this before).
I actually don't get the Glorior Belli hate. I think they're okay, they've got some nice sections with creepy riffs. But Immortal still blows them out the water.
