I'm not sure I see a difference.
The tool "needs a slot" to get the cable in, and out, so how could one be true 360 degrees?
Compressing the metal parts of the connector will have the compressed part done all the way around.
I've used a similar tool to those shown and it did the job quite well. What I liked about it over another was how it supported pressing in the coax firmly, by its shape.
One that looked more like pliers was at 90 degrees and horrible support for pushing the coax fully in.
