You're going to start a war here...

There are those who prefer Inventor. There are those who prefer Solidworks. There are those who prefer Pro-E. There are those who like other programs. They may all admit that their least favorite program has nice features. But they all really, really like their own preferred program. You aren't going to get a definitive answer.

I personally have used Solidworks and Inventor. I don't like Solidworks as much as Inventor.

There are also those who use the edit button on their posts instead of posting immediately afterwards with clarification.
