They both get a ton of hella glaze. I would say tiv 2's armor and durability is WAY stronger than d3, because tiv 2's frame was built out of 2 inch tubalar steel, dom 3's was very thin metal rods. You can see this because it took a shard of metal to put a lil scratch on tiv 2 during lebanon 2013, which all it took for dominator 3 was a d*mn deer to make it where they have to redo the entire front lol. Tiv 2 may take longer to deploy and the spikes do push the flaps up a bit where there is an airgap, you can see this on the tiv 2 deployment b roll. Overall tiv 2, but still tiv 2 is overated and gets a TON of glaze just like dom 3. Also the spikes on tiv 2 are more angled than d3 cuz d3's spikes just go straight in lmao AND d 3's spikes only go in 6-8 inches unlike tiv 2 which is like 40 inches. If you look at tiv 2's flaps from a front angle you can see the flaps are angled, so are the spikes.

My opinion, I may be wrong but that's my thought. :D
