Fanatec Full Force

As Iracing is the only sim that supports Fanatec Full Force, is it worth it? Do other manufacturers have something similar that's better? I'm very close to pushing the button on club sport DD+. I set myself a black Friday budget, spent 80% on a new cockpit and seat, buying the DD+ would take me around 150%of my budget. I know I shouldn't but if I do, will i notice a major upgrade coming from a CSL DD 8NM?
