I've been really happy with my Brittany, Junie. She's my first Brit, just turned 5 this year.
My personal experience has been very positive. She's a real people pleaser in the house, and will suck up to anybody for attention. (The opposite of my wirehair, who is very much a one-man dog.) She's settled into about a 150-200 yd dog, which works pretty well for most of the situations I put her in, and can run all day for days at that distance. I find that towards the end of the day, my friends are often putting up their dogs while Junie has legs to spare.
Compared to the other dogs I've had (small sample size), Junie has been slower to come along with certain things. She really never retrieved until last season, but once she started, she held her own just great and did a really nice job retrieving quail for us last season. A lifetime Brit fanatic told me that's pretty common for them to flip a switch at about 3 years old...
Anyway, that's my personal experience with one member of the Brittany breed. Quality hunters from my experience, and they bring a ton of joy to your home.
