Let me preface this by saying it’s great when you as a customer have different options of the same aircraft(I’m assuming this will be the case if FSLABS release their A320 series) in front of you based on your pocket size and simulator needs and of course personal preference.
The FSLabs A3XX series was by far my favorite aircraft addon in P3D, and despite the controversy they were involved in, just purely from a simulator standpoint it really set the bar of how immersive a desktop simulation can be. Aside from the system technicalities and depth, the fact that the GSX integration and ATSU operations were so realistic, and made you feel like you were part of an airline operation rather than just operating the airplane by itself in a sterile environment, really placed it above a lot of other addons in the community. The sound environment was also on a different level.
The FENIX is a great value product and their support seems to be pretty good with a lot of customer interaction. We need more of that in the community. Their aircraft model is also very beautifully done, and it seems like a lot of hard work and dedication went into even the tiniest of details. The fact that their product is priced at a level that makes it accessible to a lot of people is also a great positive.
Having said that, and please correct me if I’m wrong, it seems like FSLabs write their own code from the bottom up, and doesn’t necessarily rely on another software/platform to make their product work. I don’t know much about Prosim, but from my limited knowledge gathered here and on discord, a lot of the code isn’t written by FENIX themselves and therefore exposes them to the “flaws” of Prosim, which might be more difficult to correct at that point. This also leads me to the question of future products, if they were to venture into developing future aircraft that don’t necessarily have the Prosim framework available. But I’m assuming with all the money they’ve made from the sales, they probably have a good team of developers.
I’m very excited about the future of flightsimming, and hoping we will see a lot of new exciting products in the near future.
