An alternative good place to ask this question is r/hotas
VKB Gkadiator NXT is the go-to joystick right now.
Well designed, good component choices throughout.
It’s a traditional stand-alone desktop joystick which features a throttle on the base so would need to be coupled with a separate throttle in order to become part of a hotas system.
The choice of throttle is basically going to come down to what you fly and how.
If you fly a lot of General and Civil aviation then perhaps a throttle quadrant is a better option.
VKB now make their own which links with the Gladiator NXT and the Honeycomb Bravo is widely used and quite well regarded…
(A throttle quadrant will also serve you better if you fly a lot of WW2 prop driven warbirds so would still be a good choice for IL-2 for example)
If you fly a lot of combat jets and/or want a lot of buttons etc within easy reach on the throttle itself then a military style throttle is the option to look at. Here is where things get a little spicier as there is limited choice.
The Thrustmaster TWCS is more entry level but can benefit from some modifications. The Warthog throttle is actually ok and can also benefit from modification and the Virpil CM3 is lovely but not exactly cheap (this is where we start into “enthusiast” grade kit)
Gladiator NXT and TM TWCS or Warthog throttle if you can pick one up is often cited as the “sweet spot” right now over at r/hotas and would seem well suited for combat and space sim.
If you have a slightly bigger budget then consider VKB Gunfighter + Grip and either wait for them to release their TECS throttle or pick up a Virpil CM3
Virpil also make grips and gimbal’s. I’ve been very happy with both an MT-50 base and grip (the original variant) and the Warbird base and Constellation Alpha…but the VKB Gunfighter is a good gimbal and the all metal MCG Ultimate is an extremely sexy looking combat style joystick.
