This probably boils down to a personal choice of choosing which risks you are willing to live with. I also was doing pretty well on rotating antibiotics. Between the C. diff risk and risk of superinfections, continuous antibiotic use was not recommended.
Remember, I was already on biologics for my arthritis and my GI encouraged me to switch to Remicade because there was more data available for it. It also was combined with azathioprine (oral Imuran). Entyvio is the next step if Remicade fails. I was less than thrilled to get involved with infusion therapy and the inconvenience of it. But, it has been OK and I schedule travel around it. The main thing is that I have been antibiotic free for nearly 2 years now.
I don’t think there is any one clear answer.
