difference between available beaglebone display capes

what is the difference between

http://www.4dsystems.com.au/product/4DCAPE_70T/

and
http://boardzoo.com/index.php/bone-lcd7.html

or

http://www.4dsystems.com.au/product/4DCAPE_43/

and
http://boardzoo.com/index.php/bone-lcd4.html

are both well supported under the current debian install? how are these boards different?

Thanks,

Eric
