test-e, simply because of cost. I get similar gains from each. I usually kickstart my cycles, so I have no need for the fast acting compounds in sust. PCT should be the same for both. I wait 2 weeks after the last injection and then start the pct. The
test-decanoate in sust has a bit of a longer half life than test-e, but two weeks is a good rule of thumb for both.
I've used Sust 250 and Test Enan, both at 500 mg for 10 weeks, I got alot more swole off of the Enan than the Sust, however i got stronger off the sust. I did .25 mg of Arimidex ED throughout, and 40 mg Nolva ED in PCT.
If i had to chose again i would do sust over enanthate
