Ive been an electrician on/off for about 45-years and there is definitely a difference in electrical tapes. I have used about every type out there and always come back to this whenever I need a quality tape job that is exposed to anything like under the hood or outdoors. I have used those less expensive bulk brands because I tend to cheap out at times and I usually end up regretting it unless Im using it for something I don't care about like holding some wires together in an enclosed box. Those cheaper tapes will not hold anything for long when exposed to heat, oils, sunlight and/or cold. I wrapped some connections  in my engine compartment with this because the tape that was already there was a gooey mess and not holding anything together as it should this tape looks as good a year later as it did the day I put it on. Its pricey but well worth it if you want to tape something thatll hold. I noticed that when the power company connected my new 200-amp service they used this tape to wrap the connections for the service entrance and its holding fine in blistering desert summer heat and sub-zero winter cold.
