1954 vs 1955 Which one?

[jasonc]

OK, now that I am winding down on my 1956 topps set. I might as well think about my next postwar vintage set to start building. I have been going back and forth, and finally narrowed it down to two.
1954 or 1955?
To me it's a tossup, I have been thinking about which one for the last week.
This would be raw, low to low-mid grade.

I like the looks of the 1955 slightly better, but there is no Aaron RC (which is one of the iconic cards in postwar IMO)
1955 looks somewhat similar to the 1956, and 1954 would be a change, but 1954 has slightly more cards, and this is to be a card by card project)
No Clemente and Koufax card in 1954.
Two ted Williams cards in 1954, I am not a big fan of 2x or 3x of one player in a set.
Disadvantage would be high priced high number commons in 1955.

There are so many things to consider, which is why I am at a tossup.
For those of you that have both sets, which do you prefer and why?
Looking at opinions of which has better player content, looks of the set, etc? and how easy it is to complete the set on a budget?

Thanks for any insight.

I am at the point where I am giving the 1955 a slight edge (like a 51 to 49 edge lol)
