We didn't have two settlers in a row did we? It's settler after galley right, but yes I know a ton of things were queued, probably more than we really have decided on.
I do know I personally wasn't for the galley first but it's a little late for that. Between the next settler/worker, I think I could go with either, and they work out close to the same (settler gets more production/commerce in the short term but worker gets a little more improvement time/production through eventual chops, but they should be mostly even)
So long as it's not galley => settler => another settler, if that's the case that's too many settlers without any workers.
