I'm obviously biased and don't find anything weird about shipping the Robins with each other; I just personally find Jaydick to be the most interesting because of their canon relationship and dynamic. that being said, I'll never begrudge anyone for shipping other combos!

being a lot of people's introduction into the Batfamily. Dick and Tim are far more 'brotherly' with each other because of Jason's death; Dick's guilt over his distance with Jason before his death is what drove him to try to build a better relationship with Tim.

Tim and Jay are canonically about 2 years apart in age, fwiw. Jay and Dick have a larger gap of about 6-7 years depending on your interpretation of canon. I'm a diehard Jaydick shipper, and I think that the "sibling-coded" emphasis people try to put on them is a result of Wayne Family Adventures--
