Might sound like a subjective question, but it doesn't have to be:
This is not an actual answer to your questions, but more information on the subject:
MacBook Airs go into "deep sleep" (hibernate) when left with the lid closed for a longer while. Basically, the current state of the machine is saved to the hard drive (the SSD in the case of MacBooks) and the machine turns off, thus not consuming any power while in standby. When you open the lid, the machine state is retrieved from the SSD and restored.
So, the wake time is determined by the speed of the SSD inside the MacBook Air.
2010 MacBook Airs have SSD speeds in terms of 100 MBps, while latest MacBook Airs (2012) have SSD speeds in terms of 400-500 MBps, so wake time should be a lot faster with the 2012 models.
Comparing with the iPad is irrelevant, as iPads do not hibernate, as far as I'm aware of.
I think this might be due to the fact that some European keyboards have a different arrangement of the keys. For example, compare the enter keys and the number of keys in each row.
So my (American) keyboard layout looks like this:
What I noticed is that on your screenshot, the layout is called "USA", and on mine it is "U.S.", maybe this helps to find the correct layout.

None, to be frank. They all feel approximately the same in my opinion - the MacBook white 2010 has a lighter feel than the Pro or Air which to my senses are pretty much the same.
Both the current models and the now out of production white macbook have the same keyboard, to all intents and purposes, apart from the air and pro have a backlit keyboard which possibly leads to a heavier key press - although that might just be because my white machine is older and slightly more worn.
