If 1:200 is the scale in question, Hogan Wings is clearly the best among the 3 manufacturers named. Among the reasons: Hogan Wings have the most accurate overall appearance and a higher standard of manufacture; landing gear is also available for Hogan Wings models (and is included with some). Even so, basic details are mostly non-existent on Hogan Wings 1:200 models, though a "step up" from Skymarks and Long Prosper. All in all, when compared to models from the other two manufacturers mentioned in this topic, Hogan Wings are well worth a few extra dollars.
The main strengths of Skymarks and Long Prosper are accurate airline markings. Beyond that, the models are recognizeable as to the aircraft type, but not much more IMHO, other than their low pricetag.
In the 1:200 range of finished models, StarJets and Herpa are both vastly superior to Hogan Wings, Skymarks and Long Prosper. The difference in quality is well worth the difference in price (about $10-15 more for narrowbodies, $20-30 more for widebodies). Unfortunately StarJets has announced that their 1:200 line has been discontinued due to poor sales.
