Funnily enough, I'm in a similar position - I have an offer of Engineering at Dyson Institute, or Electrical Engineering at Imperial. In your case, I'd say it just boils down to whether you want to be an engineer or whether you want to study physics.
If you want to be an engineer, then the Dyson course has its foundations in the Warwick engineering course, which is well regarded, and there's a lot to be said for having four years experience at a top engineering firm on your CV - in the field of engineering, that is probably going to serve you better than a Physics degree would.
If you want to study physics, or be a physicist, then naturally the university route is going to be most suitable for you, otherwise you're going to miss things that the Dyson program, by it's very nature, won't offer.
I'd say there aren't really any wrong options here, all of your choices are really strong, and it's really down to where you see your interests/early career going.
(Personally, I think I'm probably going to go with Dyson as I find the practical experience to be really valuable, and I did a year at Cambridge's engineering course and found it overly theoretical.)
