Your "distinct impression" is right - there are two schools of thought, diametrically opposed.
Whatever the pros/cons of the R22, it is by far the most commonly used helicopter for training and self-fly hire in the UK.
The Hughes 300 is more stable and therefore easier to fly, but it is usually more expensive.
There's nothing else I can add to what has been written in the many discussions we've had on the forum.
Choose a good school - that's arguably more important than the helicopter type.
Good Luck with your training.
