Your use of intuition makes me quite nervous. I would much prefer that you be able to state the formula and to say that you need such and such information in order to solve. Like when they ask for the measure of an arc in geometry and you realize that all you really need for that is the central angle of the arc and the diameter of the circle.
However, while I do not really subscribe to intuition, I do believe in what I call "Data Sufficiency Jujitsu." (Apologies to all practitioners of actual Jujitsu - no offense intended). Basically what I mean is understanding certain things about data sufficiency and if you have to make a decision between answer choices based on less than a complete understanding you will want to apply certain principles such as:
1) If YOU do not understand a data sufficiency problem then you should not choose answer choice E. This is because the GMAT may be trying to bully you into picking this choice just because a question seems difficult. I would say this happens more often in geometry than in the other areas. Remember, we only choose answer choice E when we completely understand the question and we know that the information is not sufficient.
2) If everything points quickly and decidedly toward answer choice E and you are confused as to how people could possibly miss the problem, you had better look again. The answer is likely to be A or B, possibly even D...in a rare case E - in other words anything but C. Do not trust the answer C if it seems like there is no way anyone could miss the problem.
So those are a couple of points of Data Sufficiency Jujitsu.
If you really believe in your intuition then, as karanrulz4ever tells us, you it might be a good idea or a bad one depending on whether it works in practice. If you are thinking of using this on test day you need to try it before hand. Mark any problems where you use "intuition" and see if you get those right!! If you get at least 2/3 right it might be something for you to think about on problems that you do not fully comprehend at the top of your mind. Maybe you do understand it a level below...test it scientifically and see!
