Boots suck. Good connectors just have the tab be more of an inverted V shape, so it doesn't catch but you don't need to squish a hard plastic boot to remove it.
Like in the image? That's... a boot. Not a full one, but still a boot. (Side note: I'm starting to sound Canadian in my own head.) But I agree. The "snagless" ones are the best of both worlds: you can pull a cable through without it catching on anything, but still press down the plastic retention clip when the collar gets old and stiff.
