FS under Windows 10?

Hello all... I'm a FS2004 veteran from "way back"... Due to time constrains I stopped playing the game for several years, and recently I got me a new computer running Windows 10.... I was dismayed to find that FS2004 would not run under Windows 10, and I've read that FSX it's not quite smooth under Windows 10 (it reportedly crashes a lot etc.) So I just wanted to ask what are my best bets for FS games out there...? Should I give FSX a try, is it worth it? Is there any other Flight Simulator game out there I should give a try? (although I'd prefer to stick w/ something similar to FS2004, I don't want to have to "re-learn" a complete new set of commands and ways to do things...)
While I'm at it... I have a Saitek AV8R joystick which I absolutely love, yet the last few times I've used it has shown signs of being worn out, and whenever I disassemble a joystick to "clean it" it just ends up worst. I was considering to buy a new joystick, but the AV8R was meant for Windows 7, so I'm afraid it won't be compatible w/ Windows 10 either... Which joystick would you guys recommend for Windows 10...?
Many thanks in advance for your feedback and help!
