The simplest answer is; Whatever CAD works for you.
However, since I use a number of CAD products, I did post about this topic some time ago.
Last week I took the plunge and started down the path of learning SolidWorks, the Maker’s license. I still favor Onshape as my go to resource but my company has recently asked people in my role to start using SolidWorks more. So now I figure that I can use this hobby to enhance my professional knowledge. So far, I can say the learning curve is very steep but I also am starting to see the appeal of a well made piece of software that runs locally. I do not hold the same opinion of Fusion 360. While it is adequate, I am unimpressed by AutoCADs commercial practices and it shows in how they really set up road blocks to user enjoyment of their software. That is typical of the company who’s software I first started using in 1989.
