Here is a question for the builders, what is your favorite part? It can range from something you find aesthetically pleasing or universally usable.

I really like the curved slopes in all of it's configurations.  They really help define the shape of a model, expecially vehicles.

 

1X2 plate!!

I like the good ol' 2x2.  

Placing the place piece and then admiring the final product ..

 

forgot to add the part - oops : 2x2 flat.. adds smoothness

I have two favorite parts when building. The classic 2x4 brick, and my other favorite is all the different rare/exclusive pieces that come with a set.

I like the part in the build when you finally get the chance to piece together several different parts that mean nothing apart from each other, and get to see the model take shape.

One of my personal favorite parts on the side of aesthetics would be the Lion Head cutout. The use is limited but gives just about any structure a nice sense of artistic design and works with current well as medieval designs.

I've already fallen in love with the piece introduced last year of the single stud circle tile. It has so many uses despite only having one point for connection. It is one of those things Lego has needed for a very long time.

On the side of plain ol' classic versatility in any situation, it would have to be the 1x4 brick. It's the perfect size for any size of wall or most any sort of build. Of course it isn't the best for every single scenario but it usually can get the job done basically.

It may be old but I can't get enough of these....just love them so much!

I like the part where the money from my paypal is transferred into my bank account

1x2x3 slopes...the tall, skinny ones are fun to click into a build.

I've always liked the arch pieces - especially a fondness for the "tree branch" arch because they were used a lot in my old castle and forest men sets. I think since lego expanded the small slope varieties, the vehicles have become much better looking (see naf's post above).

I think the most versatile pieces allow SNOT techniques!

I have a soft spot for red slopes as used for roof tiles in old vintage house sets.

My 4 year old says the same thing.  Hmm...........

My favorite Lego part/brick are the baseplates

The Tumbler back tire.

True story: my Dodge Durango blew a tire on the 405 last Thursday. Fortunately, my Lego Tumbler tire was a perfect fit.
