Full suspension adds weight and servicing needs.
If you have to carry it, weight isn't funny. But it adds comfort and urban kerb jumping. I have a IX FS. It's a fine bike, but not light, and the fold isn't tiny. But it's a free rolling bike, and my daily fitness run on it is 11 miles, with hills. Comfort is important if you're sat on anything for an hour.
No qualms about recommending Downtubes, they're a lot of bike for the money, and you get almost instant help from the designer if you have a problem.
If you got stairs to ascend, think about the weight. It could be the key to whether or not you get suspension.
