I'm not commenting about specific company products, but you really should only trust scores from official tests.
I glanced at your other post, and you can see that your Verbal score on test day was quite consistent with your GMATPrep scores, but was markedly higher than your company test scores. That's very common. Your Quant performance was lower than normal (though again, better than your company test scores), and there might be a few explanations for that. You might have just had a bad day -- either because of bad luck, or because of fatigue or test day stress. That seems plausible in light of your recent Q50, so you're probably going to do just fine if you retake the test very soon. But as you point out, some of the paid-for official tests do not include many hard questions. They will still produce more accurate scores than other tests, but adaptive tests give more precise scores around the difficulty level of the questions on the test. If a test has a lot of 400-level questions, say, it will produce very reliable scores for test takers around the 400 level. But there will be a bigger margin of error for test takers who are far above the 400 level. Since your ability level is far above the difficulty level on those tests, you shouldn't consider those test scores to be pinpoint accurate. Really they indicate you have a very good foundation, you don't make many careless errors (which is very important), and you don't have trouble with easier problems. If you'll be doing any more work on Quant, you'll probably benefit most from practicing a lot of hard questions, since the real GMAT will normally include a lot of high-level questions, and getting better at those is what will make the difference between a Q46 and a Q50. You've taken a lot of tests already, and it's quite clear your ability level now is near the top end of the scale, so I don't think you'll actually gain much by taking more tests, unless you really need to work on pacing strategy. Good luck!
