Administrative position at a Big 4, or analyst position at a Big 5 bank? (24, Canada)

So I just received a verbal offer for a non-analyst position at a Big 4 firm (I don't want to specify which position it is, but let's just say that it doesn't require much experience nor technical skills), but I also have an offer coming from a Big 5 bank for an analyst position. Obviously the Big 4 name is more prestigious, and I would be able to work in their awesome HQ office tower downtown (better location and facility than the bank office I would be working at), but the salary, work experience, and probably work hours favor the analyst bank position. Benefits should be similar between both positions - they both offer the same vacation days, and pretty good benefits outside of vacation as well. In terms of looking at it side-by-side, the bank position does seem more attractive overall by a comfortable margin, but I do think that the Big 4 name is still making me question my decision. For those that have worked at a Big 4 before, are there a lot of non-tangible assets that can be gained simply by working at the Big 4, like being able to develop a solid network, and being able to move around departments, maybe into consulting, after a year or two? I have to make a decision by end of this week, so I'd appreciate any feedback. Thanks!
