I have tried posting on RR but discontinued it because my series got no meaningful traction, aside from the hassle of posting on multiple sites
Tapas novel and RR has their pros and cons. The audience demographic and their behaviour are also different. I think you could try posting on both sites and see which one performs better/you like more.
Tapas audience is known to be mild-mannered and nice in general. There is no rating system or integrated review system. If you have reached 250 subscribers, you can unlock tipping which allows your audience to tip you with on-site currency (ink). You can also link your Patreon and or sell merch.
However, if you like your audience to give you some more candid opinions, rating, critiques, and reviews, RR is the place. You can also swap review with fellow authors; that is how some authors grow there.
To post on RR, it is preferable to be consistent and have a lot of chapters on your hand. I heard about readers there are more interested in series that have been consistently going for a bit long, that they have no worry to read it as it seems the author won't likely to quit. Romance series are seemingly less liked on RR; the audience can be picky. There is a rating system, so be prepared for someone to abuse it and give you one-star for no/petty reason. The monetisation method there uses Patreon IIRC.
