It depends on your goals.
At securing war wins in long wars, it is the only personality that will be successful. Dragons are a must.
At pumping after wars, it is by far the best. 97 hours postwar is enough to pump 180-190 nw/a.
At gaining acres through min time, or even in the 3-7 day period, it is not the best. But that's assuming you go in comparably pumped, which is hard with non-merchant.
At playing hybrid, it is very good and possibly the best. The extra income lets you get the thieves/science/draft that you need for hybrid to work.
If you are warring against a kingdom much worse, you tend to gain a lot of acres and then the income bonus helps.
