Considering the OP specified this thread to be about "all time" performance, a lot of people are putting a ton of weight on recent years. While 2056's perfection at regionals is nothing short of mind blowingly impressive, the regionals of the 90s and early 2000s were a very different environment that the regionals today. There were a lot fewer of them and often you had several of the teams being discussed in this thread in attendance for each of them. Heck, up until 1999 there was only one winner per event. Winning a pre-alliance event carries a lot more stock than an alliance era event. Winning multiple regionals in the same year was practically unheard of. While multiple teams pick up three wins per year these days, that had only occurred once prior to 2006.

There are several teams that need a lot more discussion in this thread. Chief among them is 47 (pun intended). The 1996 rookie all stars were the Chairman's Award winners in only their second season, AND reached the championship finals. They became the first team to ever win multiple regionals in the same season and the only team to do so before the alliance era. But they didn't stop at two regional victories that year, they won three (Great Lakes, New England, Southwest), a feat not matched again until 2006 (when 1114 and 1503 won three events together). In 2000, they had one of the legendary robots in FRC history, taking 2/3 of regionals (and being the #1 seed at the other). If it weren't for a mechanical failure during the championship eliminations, they likely would have won it all. While their later years weren't quite as successful, the only blemish on 47's resume is a lack of a championship event victory. And that is mitigated by the fact the team they merged with (65) when they became Wings of Fire won it all in 2003.

Until the class of 2008, it was impossible to be on Team Hammond for all four years of high school and not have won a national championship. That's particularly impressive when you consider their rookie year was all the way back in 1996. The class of 2004 won three of them (2001, 2002, 2004). If you lower that bar to reaching the Einstein/Championship finals, you can add the classes of 2008, 2009, and 2010 to that streak. They're still the only team to hang four Championship banners, and they're credited with three of the most dominant robots in FRC history (1997, 2001, 2002).

Meanwhile, at South Windsor High School, the classes of 2009, 2010, and 2011 never experienced a single season where they didn't reach Einstein. While this streak is obviously newer, the sheer length of it is absurd. If 2056 winning every regional they attended for six years is impressive enough to land them near the top of everyone's lists, I don't see how Bobcat Robotics' streak of winning six straight division titles isn't. Not to mention they picked up victories on Einstein in 2007 and 2010.

And while they've recieved a fair bit of attention, something is to be said about the continuous success of 16. The Bomb Squad was a force to be reckoned with before alliances and obviously still is today (as a member of the reigning championship alliance). Add in the fact that not only are they a member of the Hall of Fame, but they were several times one of the Chairman's Award finalists, and you have a pretty spotless resume.
