Canson Aquarelle (used to be called Canson Arches Aquarelle) is a shade cooler, with a different but similarly torchon like texture. It is available in 310 and 240 g/m². Canson Edition Etching is closer to neutral, but has less texture than either the Turner or Aquarelle.
If you are willing to put up with a high OBA content, then there are a few bright white rough textured papers available.
I'd recommend downloading and running Ernst Dinkla's Spectrum Viz app for comparing white points and paper spectral reflectance curves.
