Not sure how many of you have noticed a recent trend of "flax bashing" based around its low conversion rate to EPA/DHA. Lately I've heard lots of folks advocate the abandoning of flax in favor of fish oil. FYI, fish oil is not the holy grail of health perfection that many have been marketed to believe.
Although ALA from flax oil has poor conversion to EPA/DHA, flax still has multiple potential health benefits:

On the potential downside of fish oil for geezers, EPA has been observed to decrease natural killer cell (NK) activity in elderly subjects, which has negative immune implications. ALA from flax was not seen to have any decreasing effect on NK:

More negative effects on immune response.. EPA suppresses prostaglandin-E2 in young subjects, and decreases neutrophil respiratory activity in older subjects:

This is not to blanketly counter-bash the fish oil proponents though. Having both flaxseed & fish oil in your diet is probably a good idea, in moderate amounts. Both have their unique benefits. If not exceeding target fat grams is an issue, these need not be taken on the same days. Rotational dosing through the week is fine; our bodies don't work on a 24-hr clock.
