I can relate to this post out of my own personal experience and I have awnsered many posts like these since I got Lady 2 years ago.
Lady turned 2 years old in november and is 3 ounces shy of weighing 2lbs.She is strong,brave,playful and is treated exactly the same way as my youngest yorkie Jess who is almost 2 years old and weighs just over 7lbs.I must admit that as a puppy,Lady DID need special treatment because she was VERY tiny and until she was 3 months old we had to watch her closely.We had to make sure she ate and drank regularly and we kept her safe from my kids (who are 6 and 9 years old).But after she turned 3 months old she was just your regular yorkie,just a little smaller
Here (spain),all pups are sold and given to their owners at around 45 days old,even yorkies as tiny as they are at this age (Im not saying this is right,its just the way things are done here).Lady was the size of a guinee pig when I got her and I must admit that back then I thought that her tiny size was normal.
Tiny yorkies are cute,but having 2 very different yorkies myself,I must say that I dont find Lady cuter because she is smaller at all
Even the bigger yorkies are still really small compared to other breeds,to me they are all adorable
Tiny yorkies DO get more attention when they go out and people always stop to ask what kind of yorkie Lady is and how cute she would look with their kids (Iv stopped explaining there are no "kinds" of yorkies now lol),but at the end of the day the only difference I find is that whilst I have to help Lady up onto the couch,Jess can jump up on her own
Would I get another tiny yorkie? To be honest,I wouldent let the size bother me at the moment of choosing,I would just look at those brown eyes and let the rest be history
