I Don't think one's better than the other, Sure Ozzy Fronted Sabbath is the Original Line Up and are total Legends for bringing us Metal, I view Sabbath as a band that fought through the years with the obstacles thrown at them [Numerous Line Ups changes etc] and probably not correct way of wording but "Moved with the times" through the years changing the Sound slightly here and there, but still keeping that Sabbath Sound [thanks to Iommi] I love all Era's of Sabbath equally Ozzy's, Dio's, Tony Martin's, Ian Gillan's stint, Glenn Hughes unintentional stint, Ray Gillen recordings of Eternal Idol, so i may be a lil biased as they are my fav Metal band of all time, but i don't compare, as they're not going to Sound or be the same, as long as they created Good music that i could headbang too lol and sing along here and there i'm happy and they did for me
