If you work with tape a lot, then the convenience of being able to tear it by hand might trump all other factors

I would NOT use this tape for heavier packages in ANY of those circumstances (especially moving), but for small to medium-size bubble envelopes and packages up to a few pounds (3 or 4 at the most), I would use this tape and have to admit being able to tear the quantity you need by hand IS a pretty cool convenience.

It is worth the higher price providing near perfect convenience.

I gotta agree with others, the convenience of tearing tape is nice, but it doesn't stick very well to my packages, normal cardboard boxes.

The convenience itself is worth it.
