I have used both systems and my personal opinion is that Visual Designer gets you started a lot quicker than LabView. So if you want fast results without too much training, I would recommende Visual Designer. But bear in mind that LabView is regarded as THE standard system in many quarters. And I must say that you do get very nice (and fast) functions. Especially if you are doing transient recording and subsequent analysis/storage. But I had to go to a specialist to have the finer details sorted out.
