I just tried the practice tests by both companies and decided to buy EnthuWare for the following reasons:
1) EnthuWare has more user-friendly GUI: the screen real estate is very well utilized, the screens look clean, and the navigation is easier and more intuitive than Whizlabs. Any text on the screen can be copied by either mouse or keyboard.
2) EnthuWare makes learning easier: After you complete the exam, the explanations are placed near the questions, color-coded, sometimes intermixed with the original text ... it's very easy to see where you where thinking right or wrong. I love this part about EnthuWare. This is even better than reading a book or doing a paper practice exam.
Whizlabs wastes a lot of valuable screen estate by placing a useless toolbar ad on top of every screen. The questions are presented in a scrollable window while the rest of the screen is mostly blank because the answers don�t take much space. I found myself constantly scrolling up and down, especially after the exam was graded and I wanted to read the explanations and learn from my mistakes. Nothing on the screen can be copied. A useless Whizlabs ad comes up when you try to copy something. After you complete the exam, the explanations are placed on the very bottom; in the same color as the original text ... it�s harder to see what you were thinking while you were taking the exam. Whizlabs should learn from EnthuWare�s solution in this regard. The constant scrolling makes learning that much harder.
The point of these tools is to learn the exam topics well enough so that it�s easy to pass the actual test. In this regard Exam Simulator by Whizlabs is not nearly as good as JWebPlus by EnthuWare. More expensive product doesn't mean you get a better product. Yes you get 12 more questions from Whizlabs (JWebPlus has 483 questions; Exam Sim has 345 + 150 = 495 questions), but that's an insignificant difference. The questions themselves are about the same in both tools and so the real differentiator is the quality of the learning experience.
