Sydney heart diet study: Seed oil group had something like 62% higher death rate.
Minnesota coronary experiment: replaced saturated fats with seed oil, cholesterol dropped, but for every 30 mg/dL drop risk of death went up something like 20%.
Several recent meta analyses also indicate no real benefit migrating from saturated fats to seed oils. The only silver lining I have seen is there is some evidence replacing them for people who have had a coronary event already. So, no, I don't think the evidence supports "seed oils do much better" in a general sense.
I don't have time to look into the sydney heart study but I know for the minnesota experiment they, not knowing how bad it was at the time, used margarine with high trans fats as the replacements. Also had a huge 95% drop out rate
Actually on a quick check the sydney study looks to be the exact same
Look at a meta review. There are a ton of these studies and the overwhelming evidence is that saturated fat is associated with CVD and ACM, PUFAs are not.
