I've re-capped dozens of devices, Tek scopes, 68k Macs, Game Gears, etc. The twist-off method really is the best way I've found to remove them, of all the methods I've used, it's the only one that I've *never* damaged a PCB doing. The key is you have to push down and twist. The guys freaking out about it have never tried it, simple as that.
Desoldering is iffy even with two irons, the leaked electrolyte affects the solder and prevents it from melting and flowing easily, also these are often on dense boards where you can't easily get to both sides without melting adjacent parts.
