MidJourney definitely struggles more with complex prompts from what I saw. If you like the output more, that’s subjective, but I think DALL•E is the leader in the space by a wide margin.
I think both have strengths and weaknesses, but I don’t disagree DALL-E in most instances is technically better at matching prompts. But I often enjoyed, artistically, the results of MidJourney more; it just felt fun to use and explore.
