What 3rd party aircrafts did you get and how do you rate them?

Reference_ FlyByWire A320(development)
fun: 9/10
quality of simulation: 7/10
stability: 8/10
FBW320 must be the best freeware in MSFS. It has the almost complete simulation to A320neo and a useful and well functioned flypad on the side. Flying this A320 is pretty enjoyed.
The stability of its avionics system is well but it sometimes cause CTDs.

Aerosoft CRJ 550/700
fun: 8/10
quality of simulation: 8/10
stability: 8/10
Fully functioned(except MCDU). Well simulated. Most bugs are fixed since 1.0.6.0. However, the autopilot is not stable on my computer. Less CTDs than FBW320. The flypad is not as good as FBW apart from fuel/payload settings.

PMDG DC-6
fun: 10/10
quality of simulation: 9/10
stability: 5/10
This model is so PMDG. Fully and well functioned. Very interesting. However, it is very difficult to handle it. Luckily, PMDG provided AI co-pilots and mechanics to help you handling these difficulties.
Even the circuit breakers are functional.
However, This aircraft can only fly VFR or VOR-VOR. GNS530(GPS) is terrible unless you purchased separately to another 3rd-party group.
Moreover, this aircraft causes lots of serious bugs causing engine failure.( after my investigation, I’m pretty sure these are bugs instead of my incorrect operation to these fragile engines)

Bredok3d Typhoon (received from SimMarket as free addon)
fun: 4/10
quality of simulation: 1/10
stability: N/A
To fly like a military pilot, my favorite aircraft is Vertigo. Then, F-22 from flightsim.to. Although I downloaded this payware, I finally removed from my simulation.
As for gauges, I like that F-22 more, although it is also a default gauges (or modified by Working Title).
As for stability, I did not tested. It never causes CTD in my scenario, but it causes crashes due to overspeed.
