I only recently started paying for zwift in addition to rouvy. There’s almost always other riders on any rouvy course that’s part of an ongoing challenge or needed to level up. There’s no lead in, you always start at the start. Each course has its own permanent standings. Zwift by comparison doesn’t take course tt to this level, but the sprints and koms are fun and good training. There’s always others out, and it is more social. I also enjoy the pace bots, that’s a great concept! Basically I ride both, and mix things up. Depends on my mood and what I feel like. I’m consistently getting faster, so it works for me currently...
