Unquestionably I'd pick the Tavor. It is the only one there designed for warriors by warriors for the realities of modern dynamic urban combat. Whether it be taking aim with marksman like precision at combatants city blocks away or clearing room to room the Tavor is simply the whole package; compact, ergonomic & modular to sum up she is sleek. Battle tested.
Where as the Swiss rifle is a front heavy overspecialized weapon that was designed for a fictional defensive war to "snipe" hypothetical foreign invaders at 600m in the Swiss Alps. Not exactly what one would call "versatile".
On the other side of the fence we have the CZ/VZ, a cold war relic with one foot in the grave that has been hastily retrofitted in an inane attempt to stave off obsolescence. Secondly I can't imagine the rifle inspires confidence with it's open falling breechblock action completely exposed to the whims of the elements and anything else that may float bye.
