Bob, I think optically they are quite similar and you can't really go wrong with either one. My understanding is that the 55/4 is no worse and maybe slightly better optically.
I think it comes down to other factors. The biggest plus to the 55/3.5 is that it can be obtained for less money. Could be a big plus. The pluses to the 55/4 are smaller size and weight. As you are aware there is a difference in filter size 100mm vs. 77mm. In my current backpack, I would have trouble putting the 55/3.5 in because of that front element.
