Which one for an Instagram post with a big headline?

Ideogram. Put the headline in quotes, ask for vertical format and discard variants with typos before polishing look. Midjourney only if you add type yourself in the editor.

Yes. Background or scene in Midjourney (no in-image type) and lockup in Ideogram, or the reverse: readable poster in Ideogram and color variants in design. Do not mix two different headlines in one deliverable without review.

Which for a client logo?

Neither replaces final vector delivery. Ideogram helps explore name + shape; Midjourney for illustrated marks without integrated typography. Legal and brand guidelines stay human.

What about a campaign moodboard with no copy?

Midjourney. Grids, stylize and --sref fit better when there are no words in frame. If one frame needs a mandatory claim, generate that frame in Ideogram.

Ideogram vs Midjourney for typography

Two image engines: one optimizes for headlines that read on the poster; the other, for steering light, camera and look when type lives in separate layers.

	Ideogram	Midjourney
Best for	Posters, packaging and logos with type in frame	Moodboards, concept art and stills without critical copy
Generated text legibility	Strong: the product leads on text rendering (ideogram.ai guides)	Weak: letters, logos and UI in image often fail or warp
Logos and posters	Poster / Logo categories; quoted copy + Layerize Text	Better as background art; names usually land in post
Visual style control	JSON with bbox and palette on 4.x; less --sref culture	Very high with --ar, stylize, --sref and variation grids
Post-generation editing	Layerize Text, inpaint and remix on canvas (text layers in beta)	Regional inpaint, remix and variations; type is not a layer
Workflow	Exact words in prompt → spell-check → text layers	Shot prompt → grid → vary light or camera → export still
Entry plan	Free with limits + paid tiers per ideogram.ai	Paid (GPU tiers; no useful long-term free plan)
Main risk	Trusting Layerize on heavy curve or decorative type	Shipping a poster headline without reading every letter

Verdict

Pick Ideogram when copy lives inside the JPG — campaign headline, packaging claim, name on an exploratory logo or signage where one wrong letter kills the mock. Use Layerize Text and quoted copy in the prompt; for repeatable layout, see Ideogram 4.x JSON in the vendor docs. Pick Midjourney when the deliverable is a moodboard, concept art or cinematic still with no critical in-image type, or when you already work with --sref and look variations: shot control stays more mature there. A common combo: explore lockup and copy in Ideogram; if the background must feel more «cinematic» and type moves to Figma, generate the still in Midjourney and set type in design.
