Magic Decking Decks

I was wondering which of the Planechase Magic decks is the best?

I recently bought the Elemental Thunder and Zombie Empire planechase decks without doing any research into which planechase deck was the best b/c I hadn’t heard of planechase before. Now I am wondering if they were good choices (I bought them b/c I love swamp decks and elemental sounded good). Me and my friends always either play 1V1 games or 2V2 (Each team shares 40 life) and only 1 of my friends beside me has planechase, so we don’t use the planes cards. My friend has the Metallic Dreams deck. Was the decks I bought a good choice or should I get a different one? They don’t seem to work very well, but then again I may just suck at MTG.
No rants, just answers. Thank you.

The most popular answer is the Zombie deck, but the red/white Strike Force deck is my personal favourite if only for its ability to completely turn around games out of nowhere.
