Drinking Rum

I've been trying a few different Rums lately:

Mt Gay XO - not bad, smooth but thin, smell isn't pleasant first thoughts were,
"is this metho" probably end up as a mixer

Appleton Estate special selection - nice, smooth, great smell, weak in flavour

Appleton Estate 12yo - OMG then best Rum I've tried to date. smooth and thick, moreish flavour could drink and drink and drink forever.
