I find that allot of characters like Gum, Pudding, Shadow, BD.Joe have excellent handling when using SPD/ACC mods so I started using these 2 mods much more frequently than Console, I don't find console mod that good.
I LOVE boost, so Ralph, Joe Musashi, Gilius, and AGES (with their Console Mods, or the Super Boost Mods for Gilius and AGES) are my personal favorites for the 6/5 boost stat. Since boost appears to be one of the better stats in the game, these are probably high up on the "tier list" too, so to speak.
