Labview has a simpler interface for quick-and-easy design with little programming experience. However, you don't have all of the flexibility in UI design you can get from a Windows Forms program.
On the other hand, if you switch to Measurement Studio .Net, you get the power of Windows (including file-writing, networking code, and vast UI options) at the expense of simplicity. Programmers will like this route better because you have a finer control over the program and it's execution, but some problems may require a bit more work to complete.
I'd suggest you try both! Even if you have minial programming experience, C# is very powerful and well documented, with tutorials available all over the internet (and the same for Visual Basic). Labview also has a big web following and lots of good print-literature to help you out. See what is most comfortable for you!
