gotbait, you will get a lot of advice here. sometimes it seems everybody likes what they own. Bottom line is unless all the different props were tested on the same boat on the same day,on the same terrain, in the same weather conditions, the results would not be accurate anyway. And on boats of different size, weight, and HP, you can't make a good comparison at all.
Don't get discouraged. Play with the pitch. you will see a difference.
A friend of mine did the same thing. he went from a stick prop to a Water Walker composite. Fired it up the first time on dry ground and it would not budge. next day backed some of the pitch out and it took right off, no problem.
Be patient, adjust the prop correctly. You'll get her tweaked.
Good Luck.
