Recommending packs is hard, because there is no objective creiteria for that. For example I am fairly certain that I would recommend other packs than Strato Incendus for example - not because one of us is wrong in any way, but just because we have different playstyles and preferences.
If you are looking for new levels to play, I would recommend creating a new thread (either in NeoLemmix Main or Lemmings Main, depending on whether you want to play NeoLemmix only). List there the packs you already played through and we can recommend similar packs.
However regarding the list in the first post: I think it might be helpful to add a tag to the NeoLemmix packs regarding which of them is available for the new-formats and which are not (yet).
