I just compiled of all the US hucards and what they used for art.
Curved text and Straight text means that the label just used the default font for tg-16 hucards, either curved or straight. Some space it out more, and some have two lines of text with the first part "resting" on top of the rest of the title underneath it. Ones that take up two lines can have either a smaller version of the same font for the words on top, or use the same font in small black letters for the words on top.
Stylized text means they used the exact same font as on the cover with only a solid color background. Sometimes the text is a different color than how it appears on the manual, but in every case I have seen it looks exactly the same otherwise. *Necromancer pointed out that sometimes the text is the same as it appears on the Japanese manual and not the US manual, as is the case with Super Star Soldier.
Stylized text with partial artwork is the same as stylized text with the addition of something other than a solid color background. Not quite full art, not quite just text. There were only 3 US hu-cards to do this.
Full art means that the hucard used the art exactly as it appears on the manual cover for its art.
