Honest verdict
Midjourney is strong, but not for the same reason as Rendervi.
Midjourney remains a very strong choice for taste, mood, and concept direction. If the goal is to make a striking single frame, it can absolutely win. But if the goal is to make architectural visuals that stay tied to the project, preserve approved views, and support production decisions, Rendervi is a better product fit because it is optimized for architectural work instead of open-ended image aesthetics.
