Each has their different challenges just like different areas of operations for the same aircraft type have their challenges.
I was a turboprop guy for many years on several types and then went to jets for a few years, back to turboprop and then back to jets again.
ATC accents can be challenging for TP guys in Europe just like in the big jets or even other areas where different languages are encountered. Weather issues can be much more critical and challenging to TP guys as ice can be a huge issue and storms cannot be topped or circumvented as easily.
To be honest, some of the turboprops have near as much info to learn about as the jet types and are much less advanced requiring much more hand flying. Several types I flew had no autopilot or flight director(of course that has changed). The ILS to ILS world of many jet operations is fairly straight forward compared to non-precision circling approaches in mountainous areas at night that is much more typical of the prop world. We did that and total black hole approaches with no PAPI at some locations onto not overly long landing areas.
Non-precision approach alternates were normal meaning that fog at your alternate ruined your day instead of being bailed out by doing an autoland.
9 legs a day was not rare and beats one or two landings a month for landing currency.
Losing an engine at V1 could be much more critical for the types that had no autofeather and the significant increase in drag. Losing an engine in cruise was also critical as speed decayed very rapidly while the prop windmilled. And we didn't have an automatic rudder input to help us.
