@The Ultimate Pawn

"Yes they are different and are strong in different regards with Issei being a power-type and Vali being a technique-type."

Actually, that's not entirely correct. Let me describe Issei and Vali's fighting styles, as I've seen them so far in the series (both Light Novel and Anime).


 * Issei is a Power-Fighter type, with minor technique-wizard qualities.
 * He primarily fights his opponents in melee range, using his superior physical prowess to "beat them down." He does, however, use his Sacred Gear abilities (like Dividing Wyvern Faery) in technique-like ways to supplement his power, or "trip up" his oppenents to give himself an opening to land a big hit.

So basically...
 * Vali is a Power-Wizard type, with minor technique-fighter qualities.
 * He primarily uses powerful Demonic Power attacks and spells to overwhelm his opponents from mid-long range, while using his superior speed & mobility to blitz them with quick yet hard physical attacks. All while using his Sacred Gear to subvert and "whittle down" his opponents with [Divide] and [Half Dimension].
 * Issei uses powerful physical attacks, supplemented by technique-oriented, wizard-like moves.
 * Vali uses powerful, wizard-like attacks combined with technique-oriented physical attacks & Sacred Gear abilities.
