Anyone who has experience with either of these please feel free to share your experiences.
I’m really curious about which one is better for mental fortitude. Though ideally, they’d make a great duo in a custom.
For me Survival Instinct wins out because it has that aspect to keep you cool under pressure, heal old injuries, and get you healthy and protect you from outside influences spiritual or otherwise. But as I said, they’d seem to make a great combo.
Perfect combo
Have used both at separate times.
For me Spartan gave me a very strong, alpha mindset which made me unruffled by what life threw at me. It was a very general and big-picture kind of fortitude and was quite stoic.
Survival Instinct on the other hand helped me gain a mindset that was not too concerned about what my health was (I have a couple of them that I used to constantly worry about). Victim mindset evaporated quickly and I was able to be confident that all my health issues will be resolved in due time.
