Thats true, sadly. I would not rank them as it depends what you are looking for and how much you know about it. Rapid is more like Maplin than RS.
RS had an extensive range of mechanical components and you needed the gallery view. Now it is impossible to find something by 'browsing' and I am not exagerating at all. I find I need to pull out old BOMs for the actual RS codes. The format of the categories on the left makes things even harder.
I hope thay have kept backups of the previous layout and be brave enough to realise they took the wrong direction. Hopefully they wont brand a drop in sales and online chatter as a 'transition period'.
