I would buy the CAD system that meets or exceeds my requirements:
The hard part is defining what your requirements are.
Typical Board
Number of layers
SMT, TH, Mixed
Hybrid
etc.
Simulation
Thermal
PreLayout floorplanning
Portability (work at home/customer site)
Etc.
Etc.
I have evaluated CAD systems and had to match the systems capabilities with our
process requirements and this is virtually impossible without developing a
matrix. You need to determine what features you're going to evaluate
(financial, team capabilities, end user issues, platform, IS support, etc.)then
weight each item on a scale (1-5 works) then rank each CAD system and cross
multiply. If you let the numbers do the talking you'll have a good start but
you need to involve the end users and let their experience guide you.
