is it the breed or the personality of the dog you like the best?

I had a Bullmastiff years ago and she had the best temperment and peronality of any dog I had.I had other dogs since,and they were no comparison.Of course they was all males,but I don't think it had anything to do with it.The dog I have now will most likely be close in temperment,once she gets out of the puppy stage.Snowball is sweet and gentle,even at her goofy stage.I've always wanted another Bullmastiff in hoping I'd have another Ginger.But I've come to grips with the fact it doesn't matter what breed of dog I have,I want the dog with the same traits,temperment,and personality.Any of you feel this way?
