Depending on where the operation is, the ATR flying is also ILS to ILS, led by autopilot. Even remote fields in europe these days are ILS equipped. If not, they have an RNP or VOR approach, which you'll fly in an LNAV overlay. I found the biggest fallacy with TP pilots is they tell themselves they are the best .. "because of the type of flying". When in reality it is Manchester/Dublin/Cork runs to Edinburgh/Exeter/Bristol .. ILS to ILS.
I have flown it and a jet, and the latter is far more challenging. There are solid reasons why you can walk from the LHS of a 737 into the LHS of an ATR, but the opposite is near impossible.
Very few TP jobs out there are actually the bush flying variety that many would have you believe it is. An ATR is not a King Air and neither are you flying among African jungles.
Ultimately, I would say what is your priority. If you've a family and want to be local, stay. If not and you want to spread your wings, the sooner you leave the prop job, the better.
