Have you had an opportunity to sit on it in a store? So often the depth is off and it can make it less comfortable depending on your height, firmness expectation etc.

RH scale is BIG so making sure you know the dimensions is important - I used to work in the RH store in Atlanta and we would always tell people to use carboard boxes and tape the floor to get a sense of size in their rooms - the high ceilings of the showroom make everything seem a lot smaller than it is

I have to say that I used to be more impressed with RH quality than I am now - I have had a few of their sofas over the years and I still have a fabulous 10 ft dining table from them with super comfortable velvet chairs that are 10+ years old and still look great - but I would not buy a sofa from them right now. I was in the market for a leather sofa and a velvet english arm sofa last year and ended up buying from Cococo Home out of NC - they could customize leather, fabric, depth, length etc and I was able to speak with one of their designers who helped me think through a few of the options - I was very happy with my experience

For the chairs and table, I would consider those if I had a RH store nearby and had an Associate working with me who I could count on if things went sideways (SO much furniture is showing up damaged these days)
