I use them all

My preferred - OpenSCAD

FOSS parametric CAD program

(Problem - GUI is from '94)

Currently using - Fusion 360

Free* to use but a learning curve for some

(Problem - uses lots of computer resources for more complex models, limited free use, ~$600/yr. to use full version)

Starting out - TINKERCAD

Excellent kid-like program to use and make great models; works great for basically everything you need, web-based, free.

(Problem - web-based only, there are limitations but you can be creative to overcome them)

Many great projects made from tinkerCAD
