Which Partridge can you relate to the most, and why?

I'm kind of like Laurie because I'm friendly and I also stand up for myself quite alot

Shirley.I wish more of the eps had been about her. Love every part of her even her toes.

I'm most like Rueben. Him & I are both big men who like to look out for other people.

Ruben was the manager so it was his job to figure things out for the Partridge Family so they could advance their career as musicians and a group.
I don't think Ruben was considered a "Big man." He was supposed to be a man of regular height who was rather funny and non-threatening.

In fact I read that his character was a man who was a "Kid hater" but he found himself managing a group made up of mostly kids and teens. That is supposed to be one of the funny things about it, irony and opposites colliding.
He had to deal with Danny a lot , who's character was wise beyond his years.

.. I do like a question like this though.
I would answer it by saying that when it comes to wanting to be like a certain character on TV ( or maybe from a novel or comic book etc) I would want to be like the character that is smartest, most talented, and has the best adventures etc.
I automatically tend NOT to like being any of the female characters because it has been my observation that even the intelligent ones are still somehow stereotyped in a major way.
Of course one character may have a certain quality I like, but another character may have a quality I like too.
In a TV show like The Partridge Family, I think I actually would like to be like Chris the drummer. He was never presented as particularly intelligent. He was never presented as the one who is the most important to the family adventures , but as far as the fictitious family, he had a very important role doing the percussion. He was in the background literally and in terms of the attention he was given (or not given) in the episodes.
I like that in a way. Otherwise, if I were in such a group and tried to get more recognition, I think I would end up feeling like I am trying to unjustifiably take the limelight from the true attractions in the group, which is the older kids, Keith and Lori , especially Keith. They were up front being attractive to the teenagers and doing the singing and even interacting with the audience.
I have found myself thinking the same about George Harrison of The Beatles. He was overlooked compared to Paul and John but it is better to deserve fame and not get it than to get it and not deserve it, so I rather be like him. Important to the group though not recognized much.

In the greatest reality though, I guess I would be fated to be more like unfortunate Tracy the "tambourine girl."
Tracy seemed to be just given the tambourine to play in the family band so as not to be "left out" and to include her out of pity rather than because of anything she could really contribute musically.

Tracy was just put in as a character so that there could be an adorable little girl in the family who was not even 9 years old yet. She was just there for scenes in which there had to be a frail young thing such as a scene in which one of the Partridge kids had to fall off a chair and be caught by Shirley's boyfriend so Shirley could feel that her boyfriend would be a good dad to her kids.
