Mario Kart is much better for casual people who have no intention of playing the game extremely competitively. It's online looks better then Brawls because it works different. It uses AI to predict where your opponents are when the games lagging and updates when it can often causing weird skips in your opponents. Annoying as hell when aiming Green Shells. The game doesn't ever slow down from lag, but it still has annoyances though not quite as noticeable. I have it, and I can say it didn't hold my interest for long. Especially since no one online wants to leave the easy tracks to play the more fun ones like Koopa Cape and Rainbow Road. Nooo always want Luigi Circuit and Moo Moo Meadows. Whoever gets the lead first can generally keep it as well by just trailing items for defense, which is slightly cheap since then only a Blue Shell or an item that hits everyone effects them. Luck plays a big part in this game as well as skill. Could be the best racer ever, that won't stop a blue shell, a red shell, a Pow Block, a Bullet Bill, another red Shell, and a Green Shell barrage from knocking from first to last 20 feet from the finish line.
Brawl is better for competitive people who intend on getting progressively better at the game. However, Brawls online is fairly limited. Also, when you start to lag the frame rate will slow down. In fighting games, every frame counts so this is the only way it'd work out. It has better staying power then Mario Kart Wii in my opinion. Also, this game is based much more on skill then luck (provided you play it the competitive way of course).
