I've had Phoenixes 2014 release of a Chongqing Airlines Airbus A319 for nearly two years but only just acquired Aeroclassics' 2015 release of the near identical model from a Waffle sale. The Phoenix version represents B-6248, whilst the AC version is B-6246, however they are both A319-133 and should be near identical. Chongqing Airlines itself is a China Southern subsidiary and has already featured in the airline history blog - see LCCs Go West: Chongqing Airlines Transforms.
As discussed in the A320 mould review the Aeroclassics mould is pretty much the best A320 family mould in town. The A319 moulds share all the same features as their larger cousins in 1/400. This means that the AC mould is a bit better all round. It is seamless and has excellent proportions. Detractions from the AC mould are the tyres on the undercarriage (far too small and not detailed) and the slightly over-sized IAE engines. The Phoenix A319 in this case is a version of the older Phoenix mould and has a small seam near the wingroot. Still it's no slouch and is still a decent mould. This version was released before antenna began to be fitted but has much better tyres than the Aeroclassics. Having said that the Aeroclassics has better undercarriage legs despite the tyres. Both moulds are perfectly respectable.
Mould Winner: Aeroclassics
What is interesting with this model is how different in detail the livery is between the two models. I should also point out that technically the two models represent different time periods since the Phoenix model has the China Southern roundel after the titles which seems to have started appearing on the fleet from early 2012 whereas the Aeroclassics version is missing the roundel so represents an aircraft from 2009-2012.
Livery winner: Draw
In many ways both these models represent the successes and failures of both manufacturers, at least with their baby buses. Aeroclassics tyres and detailing on the livery are weaknesses, whereas Phoenix's moulds, cockpit windows and quality control are inferior. In this case which model you think is better probably depends on whether you favour the mould's quality over the livery representation. I'd effectively call it a draw and both aren't exceptional examples from either manufacturer.
