I've been using the Petco generic. It doesn't have a scent per se but somehow smells.....just odd. To my nose, anyway. The cats use it but I really don't like it and have been wondering what else I can try. Maybe I'll try the A&H Fragrance Free.I buy the unscented clumping litter that Petco has available for scooping. I think it works well enough (though I haven't used many other brands) and it really is unscented.
