I bought the Phoenix (PX) model over the Dragon Wings (DW) version. It depends in what you are looking for, I value the textures and colours to be accurate so all my aircraft look the same hence, I picked the PX version over the DW. However, the DW mould is more accurate interms of the structure and wing probes, compared to the Phoenix.
As you have already picked up the DW B742 Desert stick with the DW B743 Mughal so the colours match. However, as I have a GJ PIA 777 in my collection I would like the colours to match with the two new B747s and hence the closest was the PX - sadly the DW is way to grey compared to the GJ as well as in real life. Also the DW B742 misses some of the textures on the tail hence I didnt pick it up. I have not seen the DW B743 to make a judgement though from the photos it seems the colours are the same as the DW B742.
The chose is up to you... for more views check out the two websites I gave u to see what other collectors think.
