When to choose the DO100 PRO over the DL100

In the reviewer's words

The DL100 review mentions the DO100 PRO in passing, verbatim below.

The chassis is fully metal, made out of bent aluminum sheet. It's not super thick, but it's also not as thin as on the DO100 PRO - one of their products I recently had a chance to review.
