As I never really was into DotA I cant tell if LoL is better or worse, but its definitly no bad game.
They removed all bash items. Instead you have an item with 100% chance to slow for 2-3 seconds on attack.
The amount of customization is definitly quite large, but only when you have played some dozen games, I hope at least.
30 runes with the theoretical value of 30% critical and 30 talent points for even more stuff should leave some room for individualization.
Not to forget the 2 special skills you can take into battle.
The shop is even easier to use than the HoN shop if you are new. The items seem to be a bit simpler than in the other games, though. Total lack of activateable items, therefor many different passive things.
Graphics wise it used the worse colors for the interface and the engine does not even try to hide its uglyness like at HoN.
