3D software comparison.

[SO 3D SOLID CREW]

I currently work for a company that uses solidworks, but have heard through the grapevine that other 3D systems are being looked at (not sure why).
I have heard that UG NX or Solidedge may be something we look at.

I was hoping someone on here had used either solidworks and NX or solidworks and solidedge and could possibly fill me in as to what are the benefits / weaknesses of the system compared to each other are.

To fill you in on the areas I need comparing, I currently work for a company that designs and manufactures electric enclosures, so use the following types of functionality

3D Part / Assembly modelling
2D drawing creation
Sheetmetal
Surfacing (design a few organic type shapes that fit onto the enclosures)
A little bit of eletrical routing
A little bit of large assembly
Importing of other 3D and 2D cad formats
Data Management.

I actually really enjoy using solidworks, but though I would try and get a headstart on this as I now I will be given the job of sorting it all out (
Thanks for your time

sorry if this type of thread has been posted before. Am new on here
