I was a bit disappointed that the POTP Dinobots and Predacons didn't come with swords as the weapon suited both groups.

When it comes to video games I actually prefer melee weapons as I like to get in close and hack'n'slash - I find it more visceral and fun.

When it comes to Transformers I like to see a wide variety. I liked the inclusion of a Hammer for Ultra Magnus becoming more widespread after he first wielded one in Animated. It really depends on the character. For instance Swindle should have a wide variety due to being a munitions expert, and characters like him, Megatron, Galvatron, the Seekers etc all look good with arm-mounted weaponry.

So I guess my answer is there is nothing I prefer the best, a wide variety and whatever suits that character works for me
