But I'll answer anyway.
Depends on your needs and requirements. All 3 are different and all have advantages and disadvantages. - and all have different models so it's not even just an issue about brand.
Things to consider: weight deadlift and position of lift, wheeling whilst folded, gear ratios, luggage - inc while folded, wheel size, price handling, your frame size .... durability
Don't know if they are still around but OtherHalf considered all of those plus some others and in the end went for a Tactic. Brompton probably have the highest brand recognition but they are expensive, and awkward to handle whilst folded particularly with luggage.
