The best joystick is presumably the one which gives you the most precision with the least cost. The most precise stick for the least cost is generally considered to be the Thrustmaster 16000m. The best HOTAS for the least cost is arguably the Thrustmaster Hotas X. Although these have risen in price on Amazon recently to a no-longer-bargain £40+. I'd hit up ebay. I just bagged one on a BIN for £25 inc P&P.
Last month I picked up an old Sidewinder Force Feedback 2 for £20 off ebay as well. I am very much impressed with it. I have also picked up a 'broken' X52 pro which I intend to repair and/or use the throttle with the FFB2.
At £109 you
can justify a Saitek X52 on back-order from Dabs.com but not the silly money the now practically non-existent stocks are fetching elsewhere.
The X52 is a good cheap HOTAS. Its made of plastic though and the precision of the gimbals and the springing system are questionable. Uprating the magnets for better precision only exposes the weaknesses in the gimbals so be careful there. Be prepared to do further modding/shimming. Light use, kid gloves? Should be fine.
The pro is not much better. But has a slightly less sloppy dual sprung shaft. It still has cheap plastic gimbals (identical to the non-pro) that are known to be less than precisely engineered.
A word of warning about the X52 too. They are made by MadCatz who are known for penny pinching and terribad quality control. Rumour has it that the next batch of X52 Pro's to land in the UK will be a new remanufactured version with an emphasis on better costing by MadCatz/Textron Innovations Inc. Make of that what you will.
If you can afford it I'd get a Warthog every single time. Still needs a bit of love - likely a tear down and re-lube + some finishing of the ball joint etc. But definitely the best quality consumer item at the price point. For another monkey on top of what an X52 Pro will likely cost you in the current market its a no brainer.
How much you have to spend and how much wear and tear you can live with is the big decider tbh.
If you have money to burn and don't mind a non-moving part go for the X65f force sensing stick. At least it won't wear out (in theory). Won't be much fun in WW2 flight sims though!
My FFB2 is a decade old and very well used by several previous owners and is still tight (thanks to the springless return) and accurate (thanks to a good sealed pivot design that keeps crud out of the potentiometers). It isn't a HOTAS though and I think, really, if you're in this game for the long run, you want a seperate throttle control and at least 2 8 way HATs. How you do that is up to you but there are no cheap options really. Not that will last you more than a year or so.
All of the above is entirely just my opinion obv.
Here's someone else's
opinion.
