6th Gen What are the best mega evolutions and your favorite?

My favorite are:
1. Mega Absol(It should've gained more defense or HP than Special attack though)
2. Mega Lucario
3. Mega Charizard X(don't have the mega stone yet but when I face it, it's awesome and I like it's looks)
4. Mega Blastoise
5. Mega Venusaur
6. Mega Gengar
7. Mega Scizor

The OP and best are:
1. Mega Kangaskan(This guy is pure OP and that's why I use him mostly but I'm getting tired of her)
2. Mega Mawile
3. Mega Gengar
4. Mega Lucario
5. Mega Tyranitar(Just watch it use rock polish and sweep with it's huge attack and bulk)

Well those are mine, what are yours?

My favorite Mega Pokemon based on looks: Mega Charizard X
My favorite Mega Pokemon based on competitive battles: Mega Mawile

Design-wise, I really like Mega Charizard Y. It looks a lot slimmer, and its entire body structure is just simply fierce. In terms of battling, Mega Kangaskan is one of my favorites, along with Mega Gengar and Lucario. As for least favorite, it's probably gotta be Mega Aerodactyl. It just doesn't seem to have much durability. :P

Design-wise, they're all pretty cool. Favorite in that area would probably be a tie between Charizard-X and Gengar. The Mewtwo's are pretty cool too.

As for the ones I use the most, Mega-Aggron is beast. Along with that, I've used Mega-Gengar, Mega-Mawile, and Mega-Scizor quite a bit.

Would love try out Mega-Tyranitar, Mega-Charizard X and Mega-Pinsir. Will need to get a copy of X soon.

My favorite Mega Evolutions are Lucario, Gardevoir, Kangaskhan, Charizard Y, and Blaziken.

Which ones are the best is highly debatable....

Mega Scizor Like the design of him the most.
And he can be Pretty usefull

I really like the look of mega houndoom,and its gotten me out of quite a few sticky situations. I also enjoy using megq gengar. I still have to use all the other megas though.

My favorite is Mega absol as it has the best design.
Mega Charizard Y is OP to me as I can never beat it when ever I battle one.

It's very difficult for me to choose between Banette and Mawile's Mega forms. However, if I really had to think about it, it would have to be Mawile.

I always had a bit of an attachment to Mawile, and it's Mega form is simply... fabulous. ;D

Favorite is probably Mega Charizard X due to looks. My favorite competitive is Mega Blazeikin with speed boost.
