I just started shooting the 270 maybe 10 years ago. I believe that it is as good as the 280 on most game. I shot a cow elk with a 270 this last fall and it worked well. The difference in diameter is small.
The 270 bullets cross sectional area is 0.076729 x Pi square inches.
The 280 bullets cross sectional area is 0.080656 dpi square inches.
Which amounts too about 5% difference. I just reviewed my math and it’s wrong but I believe the 5% is right.

I used to often say that the 280 had better bullet selection. Maybe it still does, but that gap is much narrower now.

My first 280 was in the 1970’s. My first 270 was in the past 10 years. The 280 is a favorite of mine. The 270 is very good too.

I think that if a shooter had good luck with one or the other they “prefer” it.

I prefer classic.
