Comparison, an ideal scenario:

Direct PR from Federal = 6 months.

Quebec Inland = 6 months (CSQ) + 1 year(Federal).

Quebec Outland = unknown number of years, I know cases which are 4 years waiting for a CSQ.

So it boils down to how many points you have. If you satisfy points in the Express Entry system currently, then its the way to go. Go ahead and apply to the Express Entry system online. Else land in Quebec with a temporary work permit & go thru the Quebec CSQ route. The Quebec CSQ is also based on points. Not every occupation is in demand in Quebec. IT certainly is.

Note: PR is not equal to citizenship. Canadian citizenship can be applied after 4 years(I think) of continuous residence in Canada after PR.
