This comes down to personal likes. I find both these jobs boring, but if you enjoy "squinting" at pictures all day looking for that minute sign that might allow us to find the enemy then you would enjoy 35G. And if you like working on electronics all day then 25U could be for you.
Both jobs lend themselves to being inside all the time. That is the main reason I would look for something else.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
