The Swans are tenth in the table during their maiden season in the top flight and have won plaudits for their expansive passing game.
“The whole package of the club is great,” Britton said. “We play football in a unique way and I think the players appreciate that.
“If you left Swansea to go to the majority of other Premier League clubs, you wouldn’t enjoy it as much – it would be a sideways step.
“The manager and the lads here are fantastic, the training is great and it’s a good environment to be part of. You would be silly to leave unless it was one of the top four.”
Britton, who is statistically the most accurate passer in the league this season, is in the process of signing a contract extension with Brendan Rodgers' side.
He did leave South Wales for a spell at Sheffield United in 2010 but returned to Swansea six months later, a move he regrets.
He continued: “It was a bad decision by me to leave, but it hasn’t worked out too badly since I came back.
“I am delighted that we have agreed the [new] deal. We shook hands on Friday and it is just a case of the club drawing up the paper work and getting the contract signed.
“I want to stay as long as I can – hopefully for the rest of my career.”
Swansea face a tough trip to Tottenham Hotspur on Sunday as they look to improve on their already impressive Premier League campaign.
