Previous reports using the R6 / 2 mouse model suggest that polyQ length may not have a direct linear relationship to the degree of pathogenicity in HD.

Conclusion: Our results indicate that two different HD mouse models have a similar deficit in response inhibition when tested on the peak interval task, although this deficit was not apparent in the BAC HD mouse line.

If either drug looks good in one HD mouse, it would be wise to test it again, in at least one different mouse model, to make sure the benefit is big enough and consistent across models — and also to look in the brains of the mice to make sure the drug was doing what it was supposed to do in cells.
