Single elimination is a A LOT of pressure. It's like the NCAA tournament. Win or go home. With these type of tourneys, you have plenty of shots to make the playoffs as long as you have the time to play. I have a job, boyfriends, and a life to attend to. It's impossible to play five bo3 tournaments just to make the playoffs. It's not the competition that defines these type of tourneys; it's just whoever has more time to invest in it. Being a veteran who knows these tiers well, by default, increases your odds of winning it all by 50%.
On the flipside, however, BO1 means that you can sort of have relatively easy paths to a victory. Take for example the difference between the Champions League and the English Premier League in soccer. They test different things entirely, and the club I support, Liverpool, has been able to win the former but not the latter. At that point, prestige and the one you want to win shifts - a club like Chelsea, that had won the Premier League but not the CL for ages, would rather that. Different strokes and such, importance depends on the person and difficulty does as well. A club like Liverpool, and certain Pokemon players, are just entirely unlikely to be able to win something where you have to be consistent over a relatively long period of time against other strong players. Similarly, some clubs and some Pokemon players are unable to cope with the pressure of a straight up knockout tournament, and fail in those regards.
So I guess overall I can't really see a distinction on the prestige or difficulty of a particular tournament when they are all so differing and test such wildly different things.
edit: Additionally, WQ, I don't think you're being the "star of the thread", considering the conversation has mostly been civil and relatively supported in anything anyone has offered so far. I don't necessarily see the downside in discussing the weight of the trophy we are two rounds away from rewarding for the first time, it's a new era and a new major trophy for a storied website, it's definitely an interesting topic and one that deserves discussion, and I'd wager that more people would find it interesting than just listing two names out of four in bold.
