The 270 offers no advantages over the 280 and several disadvantages. I didn't read many of the previous posts, but much of that was probably already mentioned.
That said, if I ever rechamber my Mauser M98 in 7X57 (doubtful), it will be to 284 Win so that I can seat the heavy bullets well out of the case.
1) .270W can be used in places in Southern Ontario where the .280 cannot
2) Everyone that sells centre fire rifle ammunition carries .270W .... not so much the .280 Rem
3) Very few manufacturers exist that do not chamber in .270W ... .280Rem ... not so much
4) Lots of cheap brass
5) 160gr Nosler Partition in .270W is a pretty potent performer.... if you have tried it.
6) .270W rifles are generally very accurate - and most people can shoot them well.
7) If you have a .270W nothing else is needed until the next useful step up - which is the .375 H&H
