Good insight here. I spend a lot of time (and budgets) on Facebook. Facebook is a lifestyle platform and it refers the least amount of buyers than any other social media platform. Still, it is extremely effective when we're talking about building a list hyper-targeted of subscribers.

What's most important is who you serve and what they want. When you can deliver this in terms that really "speak" to them, no one else's metrics matter to your business. I can give you the rundown on my clients and my own CTRs, CPCs, cost per lead, etc. but I feel like that becomes counterproductive.

For example, Promoting webinars is a lucrative strategy for some of my clients where a simple landing page (opt-in offer) converts the highest for others.
As "woo-woo" as it sounds, focus on speaking your "tribe's language" and the testing/tweaking becomes a much different (and enjoyable) process.
Unless you could explicitly verbalize how your solution is super specifically related to what your highly targeted audience is looking for right now, I wouldn't begin to weigh the different types of Facebook ad strategies.

Finally, I'll tell you we generally see a higher cost per lead on Facebook BUT we can target specific audience segments unlike any other platform so the quality of the leads tend to be much higher( and responsive). Generally speaking without knowing anything about your business, video converts 100's Xs better than text alone so incorporate it whenever possible in your testing.
