Occasionally, these settings may still lead to some odd spacing but I would then use discretionary hyphens, and/or move the slider back towards the middle between ‘Better Spacing’ and ‘Fewer Hyphens’ on an affected paragraph, and/or revise the justification settings.

Both samples use the Adobe Paragraph composer, as opposed to Single Line composer, which means that InDesign calculates the best spacing for the paragraph as a whole. Certainly, the hyphenation looks rather clumsy in the first sample.
In summary, I prefer:
