I’ve used both. Borrowed a chariot then bought a 2nd hand Burley.
The chariot I felt had a more comfortable seating system but the burley was more spacious. I wanted to be future proof so bought a two seat Burley even before we planned number 2.
No 1 son loves it, number 2 is 9 months now and going in as soon as the weather starts to warm up.
Once you get used to the extra weight and being slightly less nimble you can have a lot of fun with them!
