That's just thinking like most high-class devils. That if you have more demonic powers or magic then you can automatically beat someone who doesn't have a whole lot. Do they take into account that people without demonic powers can train and become strong like Sairaorg? Despite what you think Issei isn't a regular opponent. He has one of the 13 Longinus, the Boosted Gear and trains his ass off. You can say that gives him an edge over most of those with demonic powers. But you're treating Vali like just your regular run-of-the-mill devil who has demonic powers. Like I said, not all demonic powers and magic are equal. Saying Issei can knock away or withstand that person's magic or demonic powers doesn't mean he would be able to do it to others like Vali. Being better at magic/demonic powers than the other guy doesn't make you stronger than him. Under the same circumstances, yes. For example, if one devil is born with average demonic powers and the other is born with immense demonic powers and neither of them train or have a special ability and just rely on their demonic powers, who would win?

If the quality of Issei's power was greater than Vali's, then we wouldn't be having this discussion. Issei isn't stronger than Vali and it's presumptuous to say that Issei will far surpass Vali in the future. The quality of demonic powers should be nothing against divinity, but Sirzechs and Ajuka could beat most gods seeing as they are in the Top 10. Yes they are very exceptional. But so is Vali. Yes they are different and are strong in different regards with Issei being a power-type and Vali being a technique-type. Kiba is a technique-type yet I hear nothing of people saying he isn't strong. It's more like you are underestimating Vali just because Great Red and Ophis sound more impressive than Lucifer. You're just completely writing off Vali. Issei ISN'T Great Red or Ophis. Having a fraction of their power doesn't guarantee he's going to be as strong as those two beings themselves. Before you think that Vali won't be a match for Issei, look at Sirzechs and Ajuka.
