The problem with trying a comparison like this is the fundimental difference in character types. In DnD each character gets better at combat by virtue of leveling up. In Genesys, getting better at combat is a choice a character/player makes. A very powerful 300+ xp investigative/social character can get destroyed by a starting combat focused character.
The only way to really get a handle on what is an appropriate combat encounter is to look at your group. If they’re a bunch of mercenaries who are all good at fighting then bring on the enemies. If they’re bankers and socialites then an “easy” fight might be the most they can handle.
