Hej Badboy,
For sure, we are more than 2 interested in the answer to this question
In my airline, some captains say it's better to move to a jet as soon as you have an opportunity since experience on a jet is more valuable.
Some other say it's good to have get a quick upgrade and then wait for some training duties (line training captain, tri/e) as this can also be very quick and be a big asset when you move on.
Obviously, all the pilots I talk with have not flown a jet yet so they may not have all the elements to answer. And that's why I expect here that some of you (with more "experience") will give their opinion: for a pilot is an experience as a captain on a turboprop an advantage when moving as a FO to a jet? what is the faster track to the LHS on a jet? some say flying a jet is not as fun as flying a turboprop, in that case it might be more interesting to spend more time in the tp...? etc.
Cheers
(sorry if my english is not perfect!
