I, myself haven't heard any of the three centers you mentioned, but it is usually recommended that you stick with a center that matches the mains, from the same manufacturer.
That way they will have the same sound going across the front soundstage (timber matching), so that you won't detect any sound differences when something moves from one side to the other.
Of less importance (arguably) is timber matching the rears as well.
The best way, is to try all three and bring back what doesn't match. Of course, that is easier said, than done.
Ah, (slaps head) just realized you have Insignias. For the price, I would buy another pair and use one for the center.
