I swear by CTI. With the Upscale Deuce's Wild, reliability of light is really key. Cessaroni has never let me down. They light reliably and quickly.
Of 30 or so Upscale Deuce's launches, I only had one launch where only one motor lit, and I think that was because I didn't get one of the igniters all the way in.
CTI has a pyrogen or some sort gain in the end. Igniter lights that grain and then the motor grains fire quickly.
I've seen so many Aerotech ones not light or sputter for a while before coming up to power. I won't go near 'em, except to burn off my remaining supply in saucers.
