I'd go for the Bond option, SP MEIR with a type rating on the 135 and experience of glass cockpit. If your applying to CHC, chances are you'll be flying either an L2 or a 225 so that would also be in your favour.
From what I've been told, the Bristow IR gives you a SEIR (choclate fire guard!!) and no type rating?
Again, depends what your goal is, as a step up to a ME IR then I guess it's OK, but personally, I'd go for the real thing.
