Death Spitter vs Devourer vs Venom Cannon
TLDR: Skip Death Spitters, devourers are better anyway. Venom Cannons are good for range, as well as being better with buildings and armour. But they cost almost three times as much vs devourers.

Short Comparison of Heavy Weapons available to Tyranid Warriors and Ravenors against space marines. I set up a line consisting of: Servitor, space marine squad, dreadnaught, land speeder tempest, storm talon, and a chapel barracks.
I created three squads of warriors, reinforced them once to allow for maximum heavy weapons capacity, and then gave each of them 5 heavy weapons, one squad with all deathspitters, one of all devourers, and one with 5 venom cannons. I then started each of them down against the aforementioned line of space marine units.
Results: The venom cannons are clearly the best. They have the longest range and finished the line of space marines. The devourers placed second and speed, whereas the deathspitters were third in speed. However, the deathspitters have a very slightly longer range than the devourers. Overall, the deathspitters underperformed, as they were slower than the devourers in defeating the space marines, and require more requisition than devourers. While the venom cannons are clearly the best, they cost nearly three times as much requisition compared to a devourer.
Devourer: 15 requisition
Death Spitter: 20 Requisition
Venom Cannon: 40 Requisition
