Well, beeing two metres tall, I prefer the S92 that I'm flying over the 225, but if the company would decide to make the base a 225 only base, then I would cram myself into it and be happy about it.
There are definately good things with both helicopters, so it is not a deciding factor and if you find out you are on the wrong one, you will be able to change after a few years anyway.
Worst on S92 is autopilot, vibrations can be bad, but not so bad that some say. Good thing with it is that it is the "A" model with many nice upgrades to come, hopefully. 5 blades and the machine would be a dream for me at least.
Worst on 225 is not for me to say, but when the 50hr inspection stops including changing the engines, since their performance has degraded below acceptable, it will be a nice helicopter for shorter pilots.
Base is more important than type.
Have fun and maybe we'll meet in KSU.
