Yeah I agree, I have all the flight sims and the only 2/3 that I use regularly are Aerofly for general and commercial aviation and VTOL VR/DCS for military aviation.
As a predominantly VR user the only things I would wish for in Aerofly are:
1. just a basic ATC - even with other aircraft in FS4 I still feel like I'm flying in a "raptured" world. But I'm aware of the challenges faced with doing this
2. A map in VR - even if it's just on a disembodied floating window.
3. Controller profiles per Aircraft - or if it's simpler just multiple controller profiles - my Dash Q8 controls differ from my Airbus controls which differ from my GA controls and it's a pain remapping just to fly a different aircraft. This may already exist, but I've not found any obvious way of doing this.
4. Improved VR controller cockpit interactions - I'm not singling IPACs out on this as none of the major flight sims have got this anywhere near right. The only "Flight Sim" to have nailed this to perfection is VTOL VR. In fact I'll put my money where my mouth is and if the devs contact me by DM/PM or whatever it's called these days then I'll gift it to them just so they can see how it should be done.
Oh, and just one more very minor thing - Norwich Airport in the UK - you need to get rid of those massive 4 engine widebodies blocking the terminal building (in fact all widebodies). They wouldn't land there and if they did they wouldn't be going anywhere further, other than being scrapped and loaded onto trucks. The only commercial aircraft you get at Norwich are turboprops, small regional jets (Embraers and possibly the odd 737 if KLM or TUI doesn't have anything smaller at hand) and helicopters flying to and from the north sea oil rigs.
