Terminus, I think it depends on when you asked them! In the early days, the 92 was pretty unreliable and there were a lot of adverse comments about noise and vibration. Then they were scared after the fatal accident and the gearbox foot issue. Now that has settled down, the reliability as you say is better and since they are now scared of the 225, the S92 seems the better option to them. However these things have a habit of cycling round and at some point the 92 will probably scare someone again. Meantime the 225 having had a long absence will perhaps make its mark again!
On the subject of reliability, I think SKY were quicker to tackle annoying reliability issues, but EC are hopefully catching up and there has been a lot of work going on in the background, even whilst they are grounded, to tackle some of the recurring unreliability issues on the 225. Hopefully when it returns, the reliability stats will show its been worthwhile.
