Laundry sheets?

I would like to start using laundry sheets and wondered if anyone can recommend a brand that is really good at getting out stains.
I currently use Kirkland Ultra Clean Free&Clear fragrance free liquid detergent and it does a great job getting out stains whether using cold water or hot. Can any sheet beat this?
I tried The Clean People sheets, but nope.
Any recommendations? Must be fragrance free and as environmentally friendly as possible.
Thanks
