First off what we have established.
The current UI we have is kind of painful because of silly bevels it's encasing our build pics in.
Example:

And we would both like a more "traditional" UI.

We realize that there is probably no Spring UI similar to that. *insert sad emoticon here*
So here's an explanation of the current build picture system.

You will see that there is a blue border around both icons. Each border color has a meaning:
red = cruiser and cruiser related
yellow = economy and builders
brown = defenses
dark blue = mech and mech related
green = tank and tank related
white = plane and plane related
light blue = ship and ship related
black = submarine and submarine related
The background color is a little more straight forward.
green is ground
blue is water
very light blue is sky
green / blue is hover
blue/green is amphibious
green/brown is all terrain
We also plan to implement (see below) dark boxes in the bottom left corner to allow the user to better see how many units they have queued up. And another box in the top right corner to indicate tech level.
All this we generally agree on. Here's were we disagree.

The top is what i think it better. The bevel used in the bottom is just level of detail i think will be lost in such a small icon. Also they are not small buttons with in buttons but all part of one surface.
Sanada isn't content with either one but leans towards the bottom because:
"the human eye/brain finds gradients more appealing" and that he just wanted to "spice it up"
So that's where we stand on this. Your opinions are valued.
