I also have both and for a very long time. 1st run of LOTR new and TAF long before that. Personally I like LOTR a bit more. It's definitely a players game. Tough with long ball times and still no Valinore for me
Something else to consider, guests seem to like TAF more than LOTR. So, if you're buying the game for you, LOTR all day long. If it's for guests that are not pinheads, I'd go with TAF.
