Technical HEMI sparkplug wire removal

Surely someone has good advice for a tool to remove the sparkplug wires in a 354 HEMI ?
I've seen some Chinese made versions that look like they might work, but it's hard to tell.
Like this one; supposedly it grips the boot. But those boots are far down in the aluminum tube

 

I've had great luck just pulling on them. I think I had one pull apart many years ago. Opened up a wire puller to push them on.... Looks like those might work.

 

I just pull them. Always use electrical grease on the boots and they slip off very easily.
