There's usually a tradeoff that faces amateur astronomers. When you set out to acquire a telescope, you want images that are as sharp as possible, along with the greatest possible light-gathering. Refracting telescopes are renowned for their high definition.
Reflectors are less costly, which allows larger mirrors with more light gathering.
The problem is that large optics that give excellent definition may not be affordable. Both were aimed at the Lagoon Nebula in Sagittarius. The image in the Odyssey was brighter, as you'd expect, but the image in the refractor was notably sharper, even though this was a nebula - a diffuse object which normally isn't a good test for sharpness. A discussion over the merits of a refractor versus a reflector really boils down to how you intend to use your telescope most of the time . Since a refractor doesn't have the central obstruction of a secondary mirror, the image presented will usually be sharper than in a reflector, assuming the optics are of good quality.
