You don't have a million chances to "come back" in supply raid. Your death contributes to the enemy's point value (which gets them stronger weapons/purchasables/armor) on top of putting your team at a respawn disadvantage. Its more face paced and actually requires you to play the game instead of just sprint to boxes or crouch walk with covert the entire time.
My "problem" with survivors is I can be better than your entire team combined when it comes to aim, quickness, and skill, but one lucky down and execution sets me out the rest of the match because I don't camp and hide like a little girl. Nor did I chuck molatov and bombs the entire time.
Saying survivors is on par with any other mode is a farce. Camp fest of people running covert and crafter.
not to mention as of now, the ragequitting trophy hunters are majority in survivors, obviously because it's the EASIEST mode and when they die it just becomes ragequit after ragequit after ragequit. Glad I got my survivor trophies rather painlessly...
