Vali's normal BB is only lightly stronger than Issei's normal BB. Issei's Triaina is much stronger than his normal BB, and Sairaorg in his own normal BB one-shot Triaina Rook. Therefore, if he lands a single punch on normal BB Vali then Vali is a goner.

If Sairaorg has no knowledge on how Divide works, then it is likely Vali could get a touch in and then Divide Sairaorg away until he's at a beatable level. However, if Sairaorg knows about Divide working by touch, then it is very likely he could easily dodge Vali's touch or block it through Touki and then beat him down with only minor difficulty.

The Breakdown The Beast vs DxD L comparison is when things get fuzzy. We have a level of comparison and power to analyze DxD L with. It is around Heavenly Dragon-class going by the opponents it has fought and struggled with. However, all we know about Sairaorg's Breakdown the Beast is that it can beat a Satan-class in seconds. We have no idea of what opponents it struggles with or loses against, so there's a lack of information on one side of this comparison. Therefore, it is impossible to determine which is stronger between DxD L and Regulus Rey Leather Rex Imperial Purpure.

Going by what we have adequate information on, Sairaorg has a much higher chance of beating Vali than otherwise, so long as he knows how Divide works.

@Vanishing welsh The opinions of fanboys don't count, dude. So you're out of your league in this discussion ; )
