Are expensive strollers really worth it?

We've been looking at strollers like there's no tomorrow (I had no idea this would be so time consuming and overwhelming). My DH has his heart set on a Britax travel system (B-Agile). On the other hand, there is a Safety 1st travel system for half the cost which looks very similar.

I know that in the end it comes down to personal choice and what we could afford, but it seems irrational to pay so much more. 

Is it really worth it? Thoughts and opinions welcome.
