Raspberry Pi 4 upgrade or no?

I currently run a licensed USB server on an RPi 3 with the optimised build, connected to my gigabit network with an Ethernet cable. Can anyone (well, Michael) tell me if upgrading to a Pi 4 is worthwhile? I currently only have a keyboard, mouse, wireless keyboard/trackpad combo and a wireless Xbox One controller adaptor connected and have zero issues or complaints, but I'm thinking of getting a headset which will I assume will be a significant extra load for the server to serve, but is that within the capability of a Pi 3 server? How many USB devices can you realistically connect before problems occur? What's a good way to benchmark what your server can do?

Thanks!

The Pi4 is definitely better but the pi3b+ will handle what you are doing fine. The headset doesn't use too many resources. What uses the most is webcams via virtualhere and in that case a pi4 would be a lot better

I dont think the pi0w is much good. I get requests for cloudhub firmware for it from customers so thats why the firmware is there on my website but i dont recommend it for anything.

The cloudhubmt300nv2 is quite good for general use and the wifi works well and it can even stream webcams etc and quite cheap as well.
