Arkiv Digital, SVAR, and Genline are better than the world version of Ancestry.com, based on what I've heard, but I have no experience using the world version of Ancestry.com.
Arkiv Digital is known for its excellent images, however.
There are mantalslängder on the SVAR service but if I remember correctly, they go about as far as 1820 or so. (I haven't checked lately.)
I don't know if Arkiv Digital has them. I don't think Genline does.
