Aviattic are definitely the most accurate available on the market IMO. I have to admit bias because I know Richard (proprietor of Aviattic) well, but I recently spent a couple of hours at Aviattic HQ where he showed me his original fabric samples and some of the research he has carried out over the years. He can back up all of his colour and design choices with original artifacts. He really cares about getting this stuff as correct as possible and has devoted many years to it. Having said that, those decals you posted certainly don't look too bad. As always, your model, your choice......
