Some notes:

Regarding off-chain groups Semaphore has libraries to make it easier to have an infrastructure to manage groups. Semaphore does not have an infrastructure to manage off-chain groups. Bandada has that and also with other features such as: invite code (or link) to join a group and antisybil mechanisms to join a group.

Regarding on-chain groups, Semaphore has a set of on-chain contracts to manage groups so I would say that it can manage on-chain groups well.

In general:

• Semaphore is a protocol for anonymous interactions. It should be simple.
• Bandada is an infrastructure to manage privacy-preserving groups.
• Bandada and Semaphore are compatible, the groups are different but can be transferred from one project to the other and used together.
• Bandada makes it easier to work with off-chain Semaphore groups since Semaphore does not have an infrastructure for that.
• To join a Semaphore group sometimes you need an antisybil mechanism, Bandada has this functionality integrated.
• Bandada will help to manage really large groups because when a group has too many members it's necessary to create the merkle proof in a server instead of in the client side (browser).
• Bandada implements easily the gating mechanisms to join groups.
• Bandada makes these gating mechanisms composable (using logical operators) expanding the expressivity to join the group
