I like Line-based programming more than Labview, because for me it offers much more versatility to the program.
The reason I chose to do Labview this year was because I'm a first year programming leader, we were 3 weeks into the 6 week period, and the library was being non-compliant. My programming mentor did not mind, he really only wanted us to do what was comfortable and at that moment in time it was much more comfortable to get working code in a day than spending a week bugging out a library with only 3 weeks left.
Added to that, I had mechanical mentors yell at me for not finishing code when the robot was barely being built, and that I was not working fast enough.
Labview got them their beloved code fairly quickly.
And yet I still get flak for choosing labview, even though the robot probably wouldn't even work if I didn't.
I never win.

Anyways I digress, I say if you know labview well, as in subvi's and quick implementation, go for it. It's a neat little program for robot building, and if you're really good at it you can get a robot working in a couple days.
If you know line based code, go for Java/C++ instead. But be prepared ahead of time, because I thought I knew line based code and so did my underling, and we were extremely confused with the library. If you want to do Java next season, I suggest getting the hang of it now.
