I'm kind of confused, any reason to use one over the other?

When performing same tasks, I feel like the for-each-subnetwork has slower cooking times (especially when copy-stamping) and it's harder to properly setup, but I might missing some advantages or unique features over the for-each-loop.

What do you think?

The for-each subnet is the previous attempt by SideFX to include a looping feature. The new for-each is the current loops version. You can surround a for-each with a compile loop to regain some speed lost due to looping.

Hello, thanks for clarifying!
I can forget about the for-each subnetwork then, and will investigate the compiled loop options (-:

Cheers
