After trying some of them out, though the exchanges I used didn't screw me over, I ended up having to wait one or two weeks to get my fiat transfered to my bank account.

The only truly reliable alternative I've found is to go directly to an office (in my case the Bitcoin Embassy in Montreal) and do the exchange in person. That way I get my money right away and I don't have to stress out about the online exchange not having enough liquidity or being hacked while the money is being transfered.
