Webform is the module for making surveys in Drupal. A port aiming for feature parity with the D7 version is ongoing after substantial discussion in the meta issue linked below.
Evaluators should examine whether or not the Drupal 8 core's Contact module + Contact Storage module can do what they need, now that you can create content forms as entity types with their own fields.
While Contact and Contact Storage offer a good solution for more straight forward forms there are still several use cases better suited to webform (ability to scale (many forms/fields), client/non-technical form creation, multi page forms, complex conditional forms, submission limits etc). In this case the YAML Form module may serve your needs.
