We have a 6 month old male. He is fantastic. Not as switched on as our goldie but you can actually see the moment the penny finally drops and he gets all pleased with himself.
They are similar in that they are gun dogs except whereas a goldie is a good all rounder, setters were bred with a specific purpose so they don't have the attentiveness and same level of desire to please as a goldie but that just means training takes a bit longer, quite a bit longer. They are also really easily distracted.
He has been nowhere near the amount of work our goldie was as a puppy for biting, she was a complete land shark as a puppy, he seems to register it hurts and gets a bit upset.
He isn't as tolerant of having his walks skimped on as our goldie is. If he doesn't get enough exercise he will be bouncing off the walls and won't listen to anyone.
He is a thief and will actually steal the food out of your hand if it is at his eye level. He has learnt that tables are out of bounds but the food in hand thing is taking longer as its just too tempting.
He is gangly, ungainly, eats his own shit but we love him to bits.
His bark is hilarious.
They do need calm, firm, consistent training from day one as they are much harder to train out of bad habits they pick up. It does take quite a while for them to get the message but once they do its in. They are overall gentler than goldies (if handled correctly), not as in your face I LOVE YOU as they can be (goldies have been described as brash). Ours bowls him round the park on walks as he just can't keep up.
