Alibre Design vs Onshape: Which is best for you?

I'm using Alibre Design Pro for both machining and 3D printing projects, and really enjoy being able to iterate and improve my designs quickly, from concept through to finished product; Alibre is a good tool to have in my toolbox, at an affordable price.

Frequent errors introduced extra lines when mirroring a sketch - hard to clean up. When doing a "save as," it defaults to the last saved file rather than the file it came from, so many drawings end up in unrelated projects/files rather than the project file.

It is a "No worries" CAD system that allows you to focus on designing and not worrying about crashes, designs not saved, taking a wrong turn in a design and having to start over from scratch.

The versions when using components from different assemblies is a bit confusing, especially when created a standard parts library, then having to create a new version (V1, V2, V3 etc) when using on another assemby....
