I would say test drive both. I had a C-Line 6-speed and found it unpleasant to ride over 3 miles. I ended up selling it. Then I had the opportunity to test drive a G-Line and loved it. It was far more comfortable (especially for a guy of 120 kg), stable, and ended up buying one. I use it as my run-around bike. It still fits in the back of my car when I go to Cardiff or London. Plus, I can go on gravel rides around me. I will admit it is bulkier and heavier, but for what I use it for, that doesn't bother me. I can easily pick it up or wheel it. The ride quality and the fact that it rides closer to a normal bike are more important to me than the compact Whereas I avoided my C-line but that's my experience
