It probably depends most on where you live.
I've often used Kokuho Rose (US product). It is probably not the best but fairly easy to cook compared to some of the finer and more expensive brands I've used.
I've been told that japanese rice is the best and there are some brands available, even at Amazon.

Sushi rice is not a kind of rice.
Any short grained Japanese rice can be made into "sushi rice"
with the addition of vinegar, salt, sometimes sugar or mirin,
during a rapid cooling procedure.
In the United States, brands using California grown rice such
as Nishiki and Kokuho are fairly common and do the job.

Sushi Rice, California's New Gold Rush By KAY RENTSCHLER
Published: October 8, 2003
"The California rice industry is a stunning,
rebellious success. From a hardscrabble start-up
bolstered by government subsidies in the 1930's, it
has become a $500 million industry that is second
only to Thailand in exports of premium rice."
etc.
