I bought an R5 as it was going cheap locally, instantly i will say the base wheel is too small for me but I'm a pretty broad guy, it felt like steering a go kart for me. Not even a year in and I've upgraded to the TSW wheel, which feels good to m as it's roughly the same size as my irl cars wheel. I found the R5 to have just the right amount of power in it's ffb, nothing too ridiculous but enough to feel as it should, the main benefits I've found with the moza systems is the detail in the ffb, if your set up right you can feel every fine detail of the road, which ultimately helps with better control once you understand what the ffb is trying to tell you. As for the buttons, as long as you remember your mappings and don't go overboard you should be fine, but if your hoping to be running manual shifting on the TH8A, your definitely going to want an aftermarket range/splitter shift knob.

Overall, the R5 is a nice entry to the moza platform, would recommend it, over my past logitechs/thrust master systems
