No, not at all. Most Soviet POWs were left in open fields surrounded by barbed wire or essentially used as slave labour until they were too weak to continue working. The Germans also intentionally starved Soviet prisoners to death as part of their Hunger Plan, which was intended to divert all food resources from conquered areas of the USSR to feed German soldiers, with the intended consequence of killing as many Jews and Slavs as possible through starvation or malnutrition. The Hunger Plan was inspired by German food shortages caused by the British blockade in WWI combined with a genocidal plan to kill as many Soviet Slavs as possible to make room for post-war German colonization. Because Soviet POWs were under the direct control of German authorities who also controlled their access to food, they were the largest demographic affected by the Hunger Plan; 3 out of 5 Soviet POWs died in German captivity for the duration of the war, and most died of starvation.

I agree with both of the other commenters, but thought some perspective might perhaps be helpful.

In his highly acclaimed work Bloodlands, Timothy Snyder estimates that 3.1 million Soviet POWs were murdered by the Nazis through forced starvation as a part of Generalplan Ost. The USHMM estimates that about 1.7 million people were murdered in the Operation Reinhard camps, while another 1.1 million were murdered at the Auschwitz camps.

While many, many more people were murdered as part of the Holocaust via open air shootings, starvation, etc., it is not inaccurate to recognize that the Nazis killed more Soviet POWs through forced starvation than they did through the killing centers most people generally associate with the Holocaust.

In William Craig's Enemy at the Gates, (which the movie was very, very loosely based on) the German accounts of death marches after the Stalingrad surrender were horrific. Marched for miles across frozen tundra for days without food or shelter. There was a row of bodies on either side of the road where guards executed exhausted Germans. The German doctor telling the account claimed that a Russian guard kicked his dog to death. He slept in a warehouse and the man next to him died of frostbite. In desperation he ate a can of engine oil. And there are later claims of cannibalism at their gulags.

All of which are eyewitness, so take it with a grain of salt. I highly recommend the book by the way. It's an excellent and very personal read.

Which was worse overall? I can't offer a conclusive opinion, suffice to say that between German racism and Russian bloodlust, the eastern front was a savage, savage war.

Edit: Apologies for the Stephanie Meyer like summary by the way. I'm on my iphone, and I don't have immediate access to the book.

CORRECTION: The fellow soldier died of hypothermia, not frostbite.

Let me give you an idea how Soviet POWs were treated.

Soviet POWs were so poorly treated that, in part due to Stalin/Red Army paranoia, when they were liberated by Soviet forces, their liberators assumed that the only way any of them survived was through some means of collaboration. Thus, Soviet soldiers liberated at the end of the war were sent to the Gulag, where their conditions were scarcely better. Many liberated POWs died in the Gulag after having suffered the rigours of Nazi extermination.
