definitely slime blocks. you can bounce on them even if you had placed a carpet on top, and you can make all sorts of redstone contraptions with them

I like emerald blocks the best

Dragon egg - it is super cool and hard to get

The combined double slab stone or sandstone blocks 43:8 & 43:9

Stone bricks, dark oak planks, spruce logs, torches, and sea lanterns look nice together...

In FlowsHD texturepack, it would be the Snow-block. Very practical!

Redstone lamp

Dragon Egg

Reason: It is quite a trophy, and so far the best one from any boss. Although the wither can give you a nether star, and a beacon if you make it. The problem is only 1 dragon egg can be made.

Dislikes: It tends to teleport by it self sometimes... I had it in-cased in glass, but it was gone after 30 mins or so.

COBBLESTONE = LIFE!!!

Red Sandstone I really love that block (and the chiseled and smooth variants aswell)

.

The old block with the ID 43:6 (later changed to 43:7, followed by being removed completely from the game).

It was a full block with the texture of a stone slab on all 6 sides.
It looked good next to literally every block in the game.

(The block on the right, for those who have no idea what I'm talking about)

Stained Clays

Dark prismarine.

I just love that color.

Redstone!

It's not cool to build your house out of diamond blocks in a creative world. It's like trying to show off without actually doing any of the work. I would have to say that my favorite block would be white stained clay, because it's more of a peach-white than a true white, and makes a great skin color for pixel art statues. Anyway, no hate on diamond block houses, but it doesn't make you look cooler to have a diamond house in creative. An all diamond block house is hard to make look really good, because, besides budder and maybe iron, nothing really looks all that great with it. When you do regular old planks and glowstone you have more options, like fences and other types of blocks that match it better. Just my opinion If you want your building to look professional, just use quartz and maybe a few iron blocks. Diamond doesn't make anything seem "fancy" on creative mode.

DIAMOND !!!!!

VINES!!!
and end stone....
and stone slabs...

My favorite is the command block. #BestBlockEver

nether quartz

In my opinion dark oak wood is beautifull. I use it in nearly every map I've made from 1.7 and on ^.^

Red mushroom block

Cobblestone or Stone Brick. Hard to say.

Dark oak planks

Any stone brick product.

Well,i cant decide between iron block and obsidian

Hmmmm I would go diamond ore, cause when you find it your like OMG OMG OMG I FOUND DIAMOND ORE!!! YUSS!!!
