The T.16000m HOTAS is a great option, used it a lot for Elite:Dangerous.
The throttle can take some time to get used to since its a slider and not for the small hand. Just like most things "ergonomic" it depends on your layout. I would recommend it though, because in a sim you can never have enough buttons at hand and the little slider on the stick is not sufficient for longer play times.
I would not consider the rudder a necessity if you are mostly playing IL-2. During long sessions of Elite, the yaw twist action can be fatiguing for your wrist, but you usually dont yaw as much in regular plane flight sims. You can still buy them later, so unless there is a good package deal I would not recommend them initially.
When it comes to Logitech I dont have any personal experience. All I know is that Logitech's competing product, the X52 is originally made by Saitek when they were owned by MadCatz and some of the complaints about there quality control read like Razer^2. Though recent reviews seem to mostly critize some deadzone jitter (mostly due to them using pot's).

but im willing to pay a bit more cause i really dont like the cheap plastic
The T.16000m is pretty much all plastic, but well manufactured, which just reminded me off the review that sold me on it:
conclusion at 41:33 yeah its in depth.
