101 attack Red Katana vs 109 attack Ribgol?

Which would be faster in terms of DPS/DPM/DPH? I'm training my friend's level 135 Hero and buying equips for him (equips to save for my Soul Master), so now I have a 101 attack Red Katana and a 109 attack Ribgol. I'm not sure which is better in terms of DPS.

If I go with the Red Katana, I'll also be using a 9 str 3 dex 3 attack shield with it.

Here's the ranges with both weapons :




I know that certain places (like Gobies) would be better for the Ribgol, but how about stuff like Skelegons and Himes? Which would be better for training in places like that?

Thanks for any help you give.
