I enjoyed the CN 2 year anejo recently and it was quite good. Very nice! I'd have to compare 1921 RE and ETA side by side to make a decision.
I like the full line of both 1921 and El Tesoro but haven't tried ET's upper end options yet. I also have never tried CN 5 year anejo.
I find the 2 year to be very good to excellent and more in my price range, which is why I picked it up!
