And the winner is...

That list thing really helped. It made me realize what was really important to me. To the uninvolved reader, the lists may seem rather equal on both sides, but after looking at each item, one really stuck out. Stimulating. That was the single, most important factor for me. I think I'd get bored quicker at the smaller job. Permanency isn't everything and I was really focussed on 'can I really turn down a permanent job?'. Well, yes, of course I can. So, I believe (for the moment, at least), that I will go with the non-permanent job in the bigger place.
