Just Flight - Hawk T1, Turbo Arrows, Tomahawk, Vulcan.
Indiafoxtecho - M346, F35, F14, Tornado.
Both are truly excellent devs with great support and excel in slightly different ways. Although JF take longer to push updates as an add-on gets older, they’re never abandoned and I’m always confident they’ll get done. IFE seem to get updates out quicker.
I really appreciate the JF manuals, easy to navigate and always include a comprehensive introductory flight to get you going.
GotFriends are the easy winners: though the list includes two GotGravel aircraft from the pre-Friends days. And I haven’t discounted the aircraft that are about to be deprecated in 2024.
There are no doubt other Carenado and Inibuilds planes that I have logged purely as Asobo. But whether there are enough payware ones to challenge GotFriends…
Edit: and, of course - I should have checked this earlier - some of the GotFriends aircraft were free - six, according to my list. That would make it closer, though they’d still just pip Carenado - at least in my list - and Cowansim.
