Right there with you. If you have a better painted, themed army, you come away with the moral victory no matter the result. You can laugh in the face of people using an unpainted army, secure in the knowledge that you're awesome, and they suck.
I'm going to disagree. I thoroughly enjoy winning, and despise losing. If my army sucks because of my unit choice, that's my fault and the list needs to be reworked. When I build armies I start with a central idea. The first question is do I want a shooty, balanced, or CC army. Then I say mass vehicles, or none at all? (inbetween is strategically handicapping) Next I say resillence, or mass, or mobility? That is the core of my army, I pick units to that theme, then I pick the rest of my units to compliment them. A story can be built around that.
For example, heres my current Iyanden / Exodite army:
Shooty - no vehicles - resilient
those attributes being wraithguard (squad o 10 with warlock), and pathfinders (18)
to compliment this list I need some anti horde, some mobility, some anti tank, and some close combat.
anti horde / mobility - 6 jetbikes, 2 shuri cannons
close combat / anti tank / mobility - 4 SS, exarch, Star Lance, withdraw
close combat - yriel
close combat / anti tank - wraithlord w/ BL / EML
general support - eldrad
totals 1750. Now I have my core force (wraith guard and path finders) being resilient. Keeping to this concept I want units that are also resilient, and shooty, and compliment the army (wraithlords, IC's, jetbikes are resilient [turbo boost] and decent at shooting). Now the theme, this is easy. Wraithguard? Iyanden. Pathfinders? I happen to have some exodite conversions from a previous project so i recycled them, raptor knights being shining spears, baron in exosuit being wraithlord, psychal being eldrad. The pathfinders act as a liason between yriel (leader of the iyanden) and the baron / psychal (leaders of the exodites). They got together, they said some mon'keigh are pushing too close, we need to form a kill team to show them this is our turf, and walla you have an iyanden exodite coalition strike force.
It's themed, it's maxed out (on resilience), it's fluffy, it's fun, it's unique.
