Yes, there hasn't been a glueless patch yet that can rival a vulcanized patch. These are only meant to be emergency on-the-road repairs to get you home. Then you peel off the patch and apply the proper repair: a regular patch with vulcanizing fluid.

As for blowing a hole through the patch. The only way you can blow a hole through a patch is if you re-install it inside the tyre with the same orientation so that the patch is under the original hole in the tyre. In which case, there isn't a strong casing around the outside of the patch for it to push against. The pressure inside the tube is 6-8x higher than the outside air and it'll push right through.

This would've happened just the same if you had replaced with brand-new tube. A new tube actually has a thinner rubber layer underneath that hole in the tyre than a patched tube. And the air-pressure would blow a hole through the tube out the hole in the tyre just the same.
