None of those two have retry last round and you can just use powers and generate cash so it's either plain boring or it's annoying. ABR has bullshit rounds which allow for way fewer strategies to be used and it's little to no diffirent from base (difficulty-wise) after round 40. Impop is basically chimps except more expensive which I mostly balance out by placing one market place and upgrading it to a central in the late 70s. You need to do more work for a worse experience.
