My general experience with teams I consider to be great is quite good. I really loved going to the pits at the championship this year and talking to teams such as 118, 341, and 254. Everyone was very friendly and informative.
Overall, though, teams 1114 and 2056 are very important to 610 in a positive way. Last year, when 1114 became a Hall of Fame team, GM made a video for them (

I am the person from 610 who appears near the beginning (about 18 seconds in) and says, "Thank you 1114 for reminding us how hard we have to work", and I truly meant it.
1114 and 2056 are almost certainly 610's biggest inspirations in terms of particular teams. If they weren't around every year to remind us that winning a regional in Ontario is no piece of cake, we might not put so much effort and care into making our robots.
(I do make some generalizations about 610 in this post. This is definitely how I feel, and I assume many of the other members on my team have similar feelings, but I can't actually speak on behalf of the entire team.)
To every team who puts in a great effort every year: Thank you for always reminding other teams about they effort they need to put in themselves!
