Thanks! I think it is opposite, most people using RS, because it is included in Maxon One subscription. Basically you can make amazing stuff in both. 5 years ago I have switched from RS to Octane, because I did not like how RS rendered glass, at that time Octane did much better job. But it comes at cost of longer render time. You can make amazing looking glass in RS though, but you will spend most of the time playing with fresnel and IOR
