When I was in New Zealand last week, I was confronted by several different versions of Old Fitzgerald. Not knowing much about the product, I ended up choosing the OLD FITZGERALD 1849, but was wondering which is considered the better bottling?

The choices they had are as follows -
OLD FITZGERALD 80 proof
OLD FITZGERALD 43%
OLD FITZGERALD 1849
OLD FITZGERALD 100 proof
OLD FITZGERALD Heritage 12YO
