But one is in the weather the other is on top of it for most of the time in cruise ! Summer (dont care) Winter (Jet please)
This is a myth. Maybe some older generation props might have bumbled around in the muck but I can't remember one occasion this winter have where I have spent the flight 'in the weather'. Cruising at FL230-250 is usually nicely above anything of any concern actually. Of course, the transition between cruising level and take off/landing will involve some flight through the weather but jets have to do this too.
