When it comes to siphons, the suction that you get is going to be dependent on the diameter of the hose and the height (between the top of the tanks water level and the bottom opening of the hose).
Knowing that; all siphons are essentially equal in terms of suction (assuming hose sizes are equal). However, the real value difference between brands is not the suction, but the special features’; this can mean using flow from a tap to start the siphon, siphon priming, flexible/rigid hose, clear vs opaque, having a long rigid tube vs a short one, etc...
Hope this helps with your decision! Good question; knowledge is power.
