The regiment that did not loose a single lb?
The 51st Regiment ofc!
HAIL STALKER.
I'm waiting for Hherlev to appear and complain that the BG2 matches didn't count. 
51st were dominant for the longest I'd say (BG2 through mm and a while in NW until they got bored). They tied the 91st when the 91st were at their best and beat all other regiments I believe. All wins except 1 tie and 0 losses from what I recall.
Oh diss e-peen contest though 
Actually, we weren't at our best in MM, that came in NW.
For me there isn't one single best regiment in EU, I'd have to put them all into certain periods. The 51st were probably the strongest at the beginning, during early and mid-MM that is, the 91st then took over once NW got started and then the 92nd took over afterwards or rather was up there with the other two the entire time as they never disbanded. In general though, these three regiments when they were around at the same time, were all able to beat each other, they just never really played. 91st played the 51st once and they tied but it could have easily gone another way, the 92nd beat the 91st in MM which was also extremely close (6-4) and then we tied in NW and I believe the 51st beat the 92nd once and tied them once, but unsure on that point. So overall, pretty equal regiments. Otherwise I would really mention regiments like the 84e, 13e, 8Lr, 14e, 15e/Nr24 and the 17e. All regiments that were very good and were always extremely competitive. Nevertheless, simply as far as consistent performance goes, I'd have to put the 92nd, 91st and 51st a bit higher. They never really slipped up.
As for NA, I've only been NA for a year and a half but I'd have to say the 12th was by far the best regiment. There really was no competition. Since the 12th disbanded NA has become a lot more interesting and balanced and I'd not put any regiment at Number 1. As for before the 12th, no idea.
