Gentlemen,
We are getting into an area which doesn't really merit further discussion IMHO.
In the US, you have the luxury of comparing both kits purely upon the merits of final quality & detail.
Good luck to you whichever you choose.
Over here, the final buying decision will be made purely on price, and on that note I don't give a Fonkey's Muck about scuttle shapes, but shall concentrate my attention solely upon the final selling price.
In this particular instance, the supposed finer detail of the Dragon offering diminishes to insignificance in comparison to Trumpeter's kit and the asking price for Dragon's, especially when both finished items are viewed from a realistic scale distance away from either.
Ergo - It's Trumpeter for me.
