There is difference between the actual chakra sealed inside them.Kurama is considered the strongest from the tailed beasts...And neither Bee or Gaara come from an important clan.What are you trying to prove??what u could say about gaara who was the one tail host since he was born and Killerbee since he was a child?
Not many people can host a tailed beast.Those who can have special traits,like strong chakra to suppress the biju,strong bodies to contain them etc,etc.Big chakra reserves and strong body happens to be a trait of the Uzumaki clan.That doesn't mean that nobody else can't have those traits.
So why is Naruto a cheap version of Uzumakis or another clan??He was able to host Kurama minutes after his birth,that only proves how capable and strong his body was.
