This is the same tape they have made for the last 40 years I . I have used it for that long and it is great stuff for home or job it's strong and seals tight  the other one is scotch 88 it's the heavy version of this and it's great to.  This is not that crappy Chinese tape this is far stronger and won't rot in the sun we used it on boats in florida and it stays put .this is real electric tape not pvc .
