Even as stout as your arms are you are still more likely to rip one off then you are a top link on a 3 link.
A good 3rd link is as big as the lower links but sees far less abuse.
Realisticaly the odds of breaking either are slim,I would rather have the 3 link for better handling,more predictability,no unloading,less binding.
IMO Y links only exist because they are cheap and easy to make,they cannot perform as well as 3 or 4 link.
