Whether it's Ross and Rachel's relationship, Joey ending up alone, or that fan theory about Phoebe being a homeless woman who imagined the whole franchise... fans of the show really have had a *lot* of opinions about the characters over the years.
But there's one debate which trumps all others, and will likely rage on until the end of time. Who is the best Friends star of them all?
Well, according to rating site Ranker.co.uk - which receives 40 million visits a month - the majority of us would vote Chandler as our fave...
Yep, Matthew Perry's character, Chandler Bing topped the leaderboard of the best Friends characters of all time by over 2500 votes.
To us, it's not surprising that Chandler has a lot of fans, with his dry humour and endearingly awkward mannerisms.
But, naturally, many Friends fans will be outraged their favourite character didn't reach the top spot.
Chandler is closely followed by Joey Tribbiani (Matt LeBlanc) who sits in second place in the rankings, while Phoebe Buffay (Lisa Kudrow) comes in third.
Under Phoebe, in fourth place, is Jennifer Aniston's Rachel Green; and - here's a shocker - fifth place doesn't even go to a Friends regular, instead being handed to Paul Rudd's Mike Hannigan, who plays Phoebe's love interest and eventual husband on the show.
Courteney Cox's Monica Gellar comes in sixth place on the list, as rated by the public.
Meanwhile, David Schwimmer's Ross Gellar has landed a measly seventh place, with his on-screen dad, Jack Geller (Elliot Gould) and even Janice Goralnik (Maggie Wheeler) trailing not far behind him.
Sorry, Gellars! Ross stans are not going to be happy about this...
In tenth place is Gunther, the coffee shop owner played by James Michael Tyler who is in love with Rachel for the entirety of the franchise.
Other honourable mentions include Ugly Naked Guy (only ranked five places behind Ross...), Marcel the monkey and David, The Scientist Guy.
Of course, these rankings are ever changing, so if you don't like the sound of things, you can head to the website and cast your own vote to sway the scales.
Who do *you* think deserves the top spot?
