Inventor has benefits like built in T-Splines that is true. I hate two things majorly about it personally, holding shift to orbit is one and the sketch relations and mates are horrific also.
Just goes to show that no one package is perfect and there is so much that they could take from one another to get better. I’d love command line in SolidWorks for one, and mates in Rhino for another.
SolidWorks remains the safest choice though.
