Would you use it for your 3D print projects? (assuming you did any 3D printing)

I've personally considered it. If you're more of a visual modeller person, it very well might be ideal.

If you're a programmer, however, consider looking into OpenSCAD or OpenJSCAD:

Not only are they more programmer friendly, but making parametric models should be much easier as a side-effect.

I do use it for 3d printing projects. It's far from ideal, and doing anything precise in blender means having to learn your way around the various snap tools and the like. But it does work, and work nicely once you learn how to.

That said: you should probably learn some other programs too. Personally I use openscad and solvespace too depending on the use case.
