You will receive a very high quality of training from either establishment.

Do you want to do your training in an AS355 or an EC135? If it helps your decision making, it is generally easier to transition from a 'steam driven' aircraft to a 'glass cockpit' rather than the other way. The flip side of that is that an EC135 is a very useful rating to have in the 'parapublic' world (ie Police and Air Ambulance). Especially if your IR and type training has been done by the UK's largest operator of EC135s.
