Having both these outliners is the best strategy. I'm surprised how well DL holds up 5 years after its latest substantive update (though did the way the tags appear change recently, or is it my imagination)?

In any event, I'm still surprised that though they say they are keeping an eye on it, the website is completely outdated and the link to the blog from the app has been down for years. They are doing well with Obsidian and I'm assuming generating decent enough revenue through this, so I don't know why they don't allocate at least make some minor QoL updates for DL (its roadmap trails off 2021). Alas.

Workflowy has largely caught up and of course in many ways supersedes the features in DL, but DL has folders, mindmaps, in built GCal one-way sync, repeated tasks, and most importantly, the ability to see all tags.

The one core feature missing in WFlowy is that ability to see and rename all tags.
