It is SO good. It's a simple plane, but the insane amount of setup options, the awesome physics (pop a door open after landing and watch its behavior as you brake or accelerate), beautiful visuals, sounds, etc. Tons of configurations, including the Garmin 650 and autopilot if you want to fly a modernized one, or all the moldy old radio nav instruments if you want to go retro. And there's a nice L-2 paint with invasion strips on fs.to that should appeal to this crowd.
And nobody talks about this for some reason, but the flight modeling is about as authentic as I've felt using stock MSFS physics. And nice differences between how the stock, 85hp bush version, and float versions fly. Worth every penny.
There's also a 2020 version, just lacking the stuff only possible in 2024 but apparently a nice goodbye to the old sim and feature-packed in its own right.
