EDIT: okay, I just tried Ideogram. It's not terrible and seems to do an okay job on text generation but I'd still say its a distant second compared to DALL-E 3. However, having the ability to maintain image continuity to make refinements of your initial image based on corrections like: "Make the building larger", or "He should have a more prominent forehead" is a game changer (e.g. InstructPix2Pix) and DALL-E 3's the only one that's got it.
