The former.
In general, if you have different IPs for each uplink, you can't send
out packets of one connection through both interfaces. All packets for
one HTTP connection must have the same source address (or the peer will
drop them), and you can't generally source spoof on one of the uplinks
(the ISP might block them, due to source spoofing).
