My sentiment is this regarding Kiba & Rias being more challenging than Vidar: Vidar had heard tell of Issei from the matches but wasn't formally acquainted with Issei before the marriage interview with Rossweisse. By contrast Rias & Kiba knew a great deal more about Issei: not simply his powers & dreams; but also the driving forces behind Issei's willpower and actions. After all, a poker game is daunting against a talented player, but far harder (especially in bluffing) when someone knows any "tells" (telltale habits) you possess. Rias and Kiba knew a lot of what made Issei tick so predicting his moves was far easier than it was for Vidar.
