Which add-on for FSX is better?

I have the Project Airbus A320, A318, A319 and A321. I've heard about the Aerosoft Airbus X. Project Airbus A320 has a lot of liveries to be downloaded, but the Aerosoft Airbus X has a fly-by-wire system. Aerosoft Airbus X only had less of liveries to be downloaded, but the Project Airbus A320 doen't have a fly-by wire system. Which should i take? For me, it is a hard decision. Thanks!
