I see no contradiction.
It says the Ultramarine fleet alone could not compare to the Imperial Fist's fleet. But we know from various sources that the power of a Space Marine really lies in its Astartes and boarding action.
So while the Luna Wolves and Ultramarine fleets may be more powerful in the sense of a wholistic fleet action (IE both ship-firepower and boarding actions), in a strictly ship to ship comparison, the Imperial Fists come out ahead.
Plus the second quote only mentions the Ultramarine's ranking in terms of tonnage and firepower. If, say, strategic and tactical flexibility was how the fleets were ranked, then I bet the Ultramarines would be considerably higher on the list.
Can't judge a fish on its ability to fly, after all. At least not all fish.
