You really couldn't even compare dhc with bupe; the two are just too different. If you're after recreational effects, dhc was always my first choice - they were my intro to opiates actually. I found them very euphoric thanks to their full opiate agonist activity, and also very energy-boosting. Bupe for me is simply a substitute for heroin, it doesn't get me high. Saying that, when I did bupe when I had no tolerance, I got an extremely intense opiate body high but without the euphoria, and the effects last a long time. Don't expect those effects to last forever though; the bupe high wore off for me within a couple weeks, and I'm told this is common. The high from dhc will keep on going, as long as you still have tablets of course. They're very short lasting too; around 4-5 hours max in my case.
