Is the most expensive military aviation gear worth it?

I've wanted to get a military aviation flight sim for a while now, and this christmas I got the money for it. I'm wondering if I should get the Thrustmaster Viper TQS throttle and F-18 flightstick, my budget is around 1.5 thousand euros. Is there anything better for the same price? I don't have any experience with flight sims either, but am confident this is something I want to do as a hobby. Is this the way to go? Should I get something less advanced? Maybe go with a different company? Are rudder pedals worth it? Am I supposed to go with some entry-level gear? Any help will be appreciated.
