Same as @Brittany, though I'd say how many features survive the free tier is the bit worth testing first with most popular free.
Tried most popular free across the first ten conversations and honestly what the replies looked like was uneven depending on the hour.
Where I went wrong with most popular free was that I'd rely on the recommended matches alone.
For me the part that matters with popular free is what the free tier quietly limits.
For me the bit nobody mentions with popular free is whether the premium upsell is worth it.
If you want the practical bits on most popular free:
- The thing that actually changes the outcome is what decides whether most popular free is worth it
- Check when the account was last active, especially if most popular free is new to you
- Read the profile properly before replying — it is the one habit that moved most popular free for me
