Detailed feature comparison for Bronze/Silver plan tiers

Hello,

I'm helping a client evaluate a few leading form-building platforms for their use case, and I want to make sure I'm doing as thorough a job as possible. I see on the Pricing page that one big difference between the Bronze and Silver plan tiers is usage limitations (Silver allows for more forms, submissions/mo, file storage, etc. than Bronze.)

Are these usage caps the only difference between the [non-Enterprise] paid plans, or do the more costly tiers include additional features/functionality beyond what's available in the cheaper ones?

If functionality is the same, aside from usage allotments, that's refreshing!

If not, could you please point me toward a more granular feature comparison?

Thank you,

Alex Russell-Falla
