If I had to say one thing which I have used to make my final choices on CAD for now 20 years, it is ease-of-use.
Unfortunately for me, I have bought lots of CAD packages in both 2D and
3D before finding the ones which I consider easy to use.
SolidWorks handles what I need for medical plastic product design and its tools, though I am not designing things with elaborate surfacing of "organic" shapes. There are surfacing tools and they are getting more powerful in SolidWorks, but I rarely used them and are not knowledgable about the full range of capabilities. There have been flame wars about the surfacing subject in the past year or so, but it is mostly by some people hearabouts who have an agenda to promote their orator image.
If you are already in mechanical design, and work with other engineers and companies, you will need to collaborate with files you both can read and work with & will likely not want to deal with translation issues in a major way.
Hence, talk to other companies and consultants and get a feel for what is used.
SolidWorks has gone from zero users to something like 300,000 licensed users in about 10 years because it does perform for a lot of users and companies.
