Honestly, Burley and Chariot are both good companies with great products, and I think you'd be happy with either. I had the Chariot Couger two, and we loved it.
I think the D'lite and the Encore are both quality trailers. I'd go with the D'lite because of the better suspension, but we ride in some off-pavement situations where that is a helpful feature. If you will be sticking to smooth pavement the Encore should be just fine.
