I like the Winwing Orion 2 with Hornet grips, no buyer’s remorse here.
I don’t think I’d realistically ever change the grips, it seems like work and I’d prefer to spend my (limited) hobby time actually flying something. There’s a latch to lock the throttle handles together (unlike the one on the Warthog it’s actually usable), and that’s nice for single engine planes.
The thing that sets the Winwing apart for me is the two additional axis on the base, which I use a lot when flying warbirds.
I suspect there isn’t much to choose between the Virpil and Winwing throttles, the Virpil flight stick grips I own have been great, but for something big and heavy like a throttle shipping made a big difference - I’m in Australia and the shipping from Europe (at least last year) was simple robbery!
Edit: having never used a Virpil throttle I can’t speak to the relative quality, but the metal action in the main throttle levers on the Orion 2 is magical after coming from a mainly plastic throttle like the Warthog.
