That’s hard to say, it all depends on what you mean with “poor thickness to chord ratio”.
The twist becomes more important for thinner profiles as they tend to stall abruptly due to “leading edge stall”, where thicker profiles stall more softly by default (“trailing edge stall”) and therefore can be made more stiff and less raked.
All those effects work together, it’s very hard to make a general rule which effect will dominate in general.
A nice example of a different balance between all those effects is what is commonly referred to as the Thrailkill Twin. The Thrailkill twin softens the stall characteristic using the “biplane effect” where one fin stalls later than the other. This allows to create thinner and stiffer upright fins while still being forgiving.
