I have a soft spot for those small glaucous green plants.
Here's a couple of closeups that are helpful from the standpoint of identifying hairy Echeverias.
Spreading or splayed sepals (a setosa or harmsii trait)
Sepals pressed up against petals (a pulvinata trait)
For the record, the last plant is a cross of two different species (setosa x pulvinata) but apparently the pulvinata trait dominated. I can see how this feature will be useful to sort out the database, because we have at least one example of a hybrid misfiled under setosa at the moment.
