Ok, sorry to type cast. I like egg beaters. Honest.
Anyhow, I get that the question is quite broad and without wishing to get too deep in the weeds, I'm keen on either the AW139 or the EC175. I'd be interested to know about the ease of finding suitably type rated crew (UK ops); and from those who fly them, the quirks, good and bad.
Throw into the mix some other wild cards if you like.
