There is allot of comparisons made between the 280 and 272.
In reality they are as quick as each other, what the 272 lacks in power it makes the deficit back with the 7 speed gearbox.
I run a 280. The slightly higher revs at cruise speed is not noticeable as the engine is quiet and refined.
You don't have a "gpf" on the 280 where as the 272 has one.
The 280 has a valved exhaust where as the 272 does not.
The 280 runs x8 fuel injectors to the 272 x4.
There are not many 280's around second hand but loads of 272's.
I think the 280 will be more collectable in my opinion. Prices are almost the same.
I am having mine mapped soon with some additional parts fitted and looking to see 400bhp with a stage 2 map.
