@safetyblitz - there is no doubt that Bakari has made a bigger contribution on-field so far. He has the height, strength, and (moderate) speed necessary for a possession receiver. He has also benefited from playing the short-side WR position, where the VAST majority of WR passes are thrown in the CFL (notice I emphasized WR over SB, two VERY distinct positions, and I wish reporters, journalists, and TSN crews would continue to differentiate between the two. Also, don't get me started on the "Free Safety" garbage - in the CFL, there is only ONE position of Safety; in the NFL and NCAA there are TWO: the Strong and Free Safeties). Bakari is a tremendous down-field and LOS blocker, and is turning out to be a valuable leader for the team.
Giguere, on the other hand, was relegated to the wide-side WR position, and had few (if any) balls thrown his way with any consistency, has blazing speed, is a terrific down field blocker, has a build that is the envy of some linebackers, and has done EVERYTHING the team has asked him to do (punt/kick returns, ST coverage and blocking, decoy routs, etc). While he doesn't have Bakari's height, 5'11" is nothing at which to sneer, as his speed and strength more than make up for it.
Both receivers have done their best to make the most of their situations. Sometimes, a change in scenery, be it a new team or a new position, can revive a (somewhat) stale career. For Sam, this meant a move to Montreal on a one-year contract. For Bakari, right now he has moved into the Slot while Luke Takser heals up his "lower body injury", and from the sounds of things, he had an excellent game playing that position. Put it this way, if you play SB, you, as a receiver, get to HIT SOMEONE, and you don't get many opportunities to do that.
