Take the jet while you are still younger than the captains you will be flying with. Upgrade on the Embraer and your next move into the left seat of an A320/B737 will a much smaller step.
However your next thread may be asking about A320 Captain vs B777 F/O.
Few serious airlines these days have turbo props in mainline, they get passed off to separate feeder companies with far lower terms and conditions and often little or no prospect of advancing across.
If you have career ambitions getting onto a jet asap is what counts, this part of the world is virtually all jet, I can't remember the last time I saw a TP in Hong Kong.
Turbo prop command would be better for a pilot close to retirement and happy where he was.
An older turbo prop Captain may be seen as less desirable than a young jet F/O who is easier to teach and less set in his ways.
