The combination I'm using includes a 1.25x converter matched not only to the type of lens I am using, but to the actual lens. They have the same serial number. With the 1.25x I lose 2/3 of a stop. with a 1.4 you lose one full stop. It is raining here this morning. so fairly dark. At F/7.1 on a D500 I was limited to the center focusing spot. I prefer using the joystick to select my focusing spot, so that's a down side for me.
Some folks do well with 1.4, 1.7, and 2x converters. I seldom, very seldom, go beyond a 1.4x. If just getting into them I would say 1.4x is the best choice. They work best on long prime lenses and of course the larger the maximum aperture the better. I have never used anything but Nikon converters on Nikon lenses so I can't comment on other brands. Be sure the converter you get is compatible with your lens. In some cases the rear element of the lens can come in contact with the converter. Then you may have to open your wallet wide.

Agree, I don't think you can go wrong with the Nikon 1.4...of course, hooked to Nikon, but I've shot with a Sigma with good results, it's the TC that's the key...
