Have sailed on both Infinity 3/28 and Galaxy (Feb. 1999) and enjoyed them both. Galaxy was our first cruise so of course we were in awe and will always have found memories. At the same time we loved Infinity. I did not feel that Infinity was too big or hard to get around or too crowded at any time. As for staff, same great service on both. Much of the Infinity staff have been on the other ships and I never heard them make any negative comparisons. The only comment I did hear was from the maitre 'd in the SS United States and that was that Infinity was a much better built ship that could withstand much rougher seas without creating a lot of movement and he felt that was better than on the other ships.
