The Groundbreaker is a great option for those just getting into backpacking as it is easy to pitch, durable, and has ample ventilation. The tent weighs 4 lbs 13 oz for its packed weight, compared to the Passage 2 which is packaged at 5 lbs 2 oz (this includes a footprint, which is not included on the Groundbreaker).
One thing to consider is that the Groundbreaker's packed size in the stuff sack is 22"x7.5", meaning that it's going to be a little long as compared to other backpacking tents which average around 17-18" in packed length. So you'll need to be considerate of the extra length when packing.
Hope this helps!
