Overall, I'm a fan of 3M's electrical tapes, including their Super 33+.
However, the 33 is much more "tacky" than the Super 88. If your application may involve removing the tape at some point, or if you're using tape for temporarily holding something in place, then I would strongly recommend you don't purchase this version (Super 33) and buy the Super 88 instead. My experience is the 33 is much more prone to leaving behind undesirable sticky residue - the kind that discolors or leaves marks on certain plastics and other similar, smooth surfaces. I've not had that problem with the 88 tape.
When I say "tacky" and "residue" of the 33 tape, I'm talking about remnants of the glue on the back of the tape. It's colored black and you'll have a difficult time getting rid of it when it decides to adhere to something you don't want it stuck on.
The downside is of the 88 is, of course, it's significantly more expensive; and for this reason if I only require a basic tape that isn't going to be removed (at least not by me), then I'm more likely to use the 33. However, if I have an application where I know the tape will likely be removed in the future (say, a temporary electrical hookup for whatever reason), I strongly prefer the 88 tape. This is especially true of outdoor applications. The humidity and higher temps outdoors seem to increase the tackiness the 33 tape leaves behind. YMMV.

For any taping – fixing – insulating job, having the right product is significant to the overall success of the undertaking.Reviewed in the United Kingdom on October 16, 2020
The 3M Scotch© Super 33+ is an ideal vinyl electrical tape for a wide range of indoor/outdoor applications.
I needed some black insulation tape for low voltage electrical applications and for general purpose jobs.
· Adhesion is good - tensile strength - stretch and flexibility are fine and the best part is it does not appear to leave adhesive residue behind.
I plan to buy more and would recommend this tape to anyone in need of a durable/quality electrical tape.
