Get the 3.73 I don't think you will be sorry.
I doubt you could even tell the difference between 3.55 and 3.73 with the 10spd.
I have 3.55 in mine and I think rpm is only 1500 at 60mph, can't even tell hardly if its in 9th or 10th
Edit
One thing, you are coming from an 2011 model and I came from a 2010 which I absolutely love and bought new I am pretty disappointed in the 2018 as a whole it isn't near the quality I expect IMO.
