The best Ive used by a mile was Reflex XTR. Admittadly this was a while ago and I have not flown the updated versions of the others. Whether significant upgrades have been made im not sure.
The sims I have tried are Reflex XTR, AFPD, G3, Clearview.

The helis in Reflex XTR were BY FAR more realistic than the others.

I also thought the Fixed wing were much better too, also the graphics.

Fact is Reflex XTR is developed in Germany. This is a USA site so I would expect (but not guarantee) that there are more USA developed Sims used by members of this form, then possibly UK sims flown in the USA.

Ill be watching this thread closely though as Im looking to upgrade. But without trying them all I was still leaning towards Reflex.

We need someone that has flown them all in there UPDATED versions.

There was a good site online with reviews of them all, but its out of date now since theyve all had updates to the sims.
About time for another review of all the major sims in their latest versions.

Sorry not by me, I dont want to pay $1000+ to try them. It would require someone with access to them all.

The updates for Reflex are limited but free. G3 has 5 add ons, plus 2 expansion packs. At $30 each that equates to $410 USD for the sim and all the updates. Compared to Reflex XTR $200 with updates.

Just a thought.
