MSc Management at LSE (new one year programme) vs MSc Economics and Strategy for Business at Imperial?

Hi, I'm having a hard time trying to decide between accepting an offer for MSc Economics and Strategy for Business at Imperial or MSc Management at LSE (it will be the first year they are running the one year MiM). Any advice would be greatly appreciated!

I've broken down my thinking on each as follows:

I feel LSE has a stronger alumni network as well as brand name and it will enhance my CV more, particularly because I will have both LSE and Imperial on it instead of just Imperial (I am currently finishing an Engineering undergraduate degree at Imperial). However, I have heard that since studying a MiM is like doing a mini MBA, which may make me less likely to be accepted onto an MBA programme in future and firms will also be less keen to pay for my MBA. Another potential negative for the LSE course is that this is the first year they are running the one year MiM as they previously only had a two year programme. This means that I would essentially be in the "guinea pig year."
I feel I will be more interested in the content of the Economics and Strategy for Business Masters at Imperial and I think it may actually be the better programme, particularly since the MiM at LSE will inevitably have teething issues. The programme also seems to be more dense than the LSE one so I would be getting better value for money and learn more, but this also makes the course tougher, which is confirmed by alumni.
Essentially, I think it comes down to image vs. interest. Of course it's not really as black and white as that since I do actually like the LSE programme and Imperial Business School does have a strong reputation.

To put my decision in context I have two main reasons for doing a Masters:
To get my foot in the door at top consulting firms and other job interviews down the line.
To learn about business and gain the skills needed to make a strong start to my career

Thanks in advance for any advice.
