Choose two to four published tools. Empty attributes remain visibly unrecorded rather than being guessed.
Comparison builder
Build a two-to-four tool shortlist.

Select at least two published tools.
Use comparison to review tradeoffs, not to manufacture a universal winner. Start with the attributes that matter for your task.
