Which do you think is a better book The Return Of The King or A Memory Of Light?

[Michael]

Which has the better battles, the better ending....etc

[Peter]

Jesus, Michael!

They are two different stories, based on two different worlds, with two different endings.

WOT ends in a battle, and a few loose ends. LOTR ends long after the battle and ties up the loose ends. You might try reading them and making your own judgement. They are both excellent examples of epic fantasy.

If you are after battles, you might like to look at military fiction.
