Like all such non-quantifiable comparisons, it depends. What kind of DR? DR/magic will be effective far less often than DR/cold iron, for example, and even less so if the campaign is one where most enemies are intelligent and use weapons. Blindsight is a very powerful ability, with blindsense less so, but again their usefulness will depend on the campaign. The benefits of enlargement will be useful in almost every campaign, but for these others you have to judge based on your own campaign.
