Which one do you prefer to use? tribon or napa

[phonix2006]

I have been working with tribon for several years but it is very time consuming and complicated process to model a fair surface in tribon. Hull and structural modeling is too overwhelming, also tribon is not graphical and user friend software.
I have never used napa till now. is it a right decision to use napa instead of tribon?
Is really working with napa is easier than tribon?
Can we save much more time by using napa?
