I've seen threads about people's thoughts on the best UU (usually coming down to Keshiks v Camel Archer or Longbow v Chu-Ko-Nu's) but I'm more interested in what UU you would prefer for your play style. I think it's more meaningful then who is best, since yes, Keshiks are amazing but other UU's fit my, and probably your, playstyle better (such as Naval/Coastal Warfare). For me, the Berber cavalry has probably saved me almost all my games with them. 25% combat bonus for friendly territory and 50% for desert (both of which carry over) is phenomenal. I haven't tried it with the Order 's Patriotic War, but that just sounds like silly overkill. This Morocco UU is perfect for my more defensive game play, since I focus on trade and diplo, and comes when ideologies come into play. Each time I've gotten these guys, my neighboring autocrats or commies decided to wage war and inevitably lost, although outnumbering me, because of how powerful this unit is (also because the AI sucks at warfare). Notable UU's for me are probably also the Berserker (come earlier than their counterpart and great mobility/amphibious capability) and Seabeggars (3 free upgrades that carry over and great for taking cities) who are both nice for coastal warfare, which I find myself in more often than other types.
