COMSOL's big advantage is it ties together a lot of different physics regimes together and makes it very easy to couple different physics together. Want to do coupled structures/fluid? Or coupled electromagnetism/mechanical? Its probably the easiest one to use. Each individual physics regime is not particularly good on its own - there are far better mechanical, CFD, electromagnetism, etc solvers out there - but they're all made by different vendors and don't play nicely with each other.
