I play 4141 LK and OHKO monsters just fine. 1144 AC with similar gear only has higher AC... and less points wasted in AP and DX (and LK for PvM since you only need so much to hit monsters). If you want a great balance between survival and damage, 1144 AC is fantastic, especially with some of the crazy gear that's available now.
I don't like the 2143/3142 builds, personally, but since most of your important stats will come from gear anyway, some people prefer that leg up from having a 2 instead of a 1 (or decide they don't need the extra stats from having a 4 in a stat type instead of a 3). Eh, preference and funds/gear availability... and players have shown that they work just fine anyway.
Temp inactive again...
