well what is your lifestyle? border collies are not for just anyone, not to mention there are 3 strains of BCs working(the true BCs), conformation(the fluffballs) , and sport(usually supper leggy, and almost never fluffy) you have to watch very carefully where you go for one, would reccomend the working ones as if they come from a good breeder they are much steadier, they CAN hike for miles and miles, but they are also willing to relax at your side, they also tend to be smarter, and there is more variety to choose from. the sports strain has a very big tendency toward bahaiviour issues, because they are bred to have an insane temperment so they run faster, non of the sport breeders I know of take temperment into real consideration unless the dog is too calm lol the conformation strain from what I am told are more like golden retrievers then BCs. I dont know anything about the other breeds, but you may want to narrow down what exactly you want in a dog lol
