Pros
Pro Easy CAD model exchange
Because Solidworks is so used, most companies/universities/research institutes have at least some licenses for it, even if it's not their main CAD program. This facilitates exchanging CAD models in native formats between institutions.
Pro Advanced modelling
Solidworks is one of the most advanced, commercial CAD applications on the market today. For solid modeling, it uses a parametric and feature-based philosophy. Its operations library is enough to build the products/objects that most designers/engineers will ever need to model.
Cons
Con Expensive for individuals and freelancers
Solidworks typical clients are big organizations, so buying licenses can be quite expensive for individuals. Usually they only sell them in packs and will only give quotations when requested directly.
Con Weak analysis modules
Solidworks has analysis modules ( structural, thermal, flow, ... ), but they are quite simplistic and their solving abilities aren't the best, so analysis results should be looked at with a critical eye. These modules should only be used for preliminary analysis.
