I would go for job "B". The job market is not like what it use to be. I doubt you'll stay at job "A" long enough to reap benefits and you could (assuming the are both the same kind of work) work for job "A" later on. The days of a gold watch and a pension are long gone and employers do not put long term investments in their employees.

I'd take "B" for what you can get out of it and then take a look around when you are in a better position. Night, weekends, less pay, no benefits... sounds like a lemon of job. Promises of advancement are just sweet nothings, pay is real.
