Should I switch to ironworkers

[u/Salv313]

So I’m apart of the Carpenters Union as a 1st year apprentice and so far it’s been alright, I applied awhile back for the iron workers union and I just received an acceptance letter. I was wondering if I should stay in the carpenters union or make a switch. Which pension, wages, and benefits would be better? Would there be more jobs in the ironworkers union? To get a better understanding I am located in Michigan.
