In places where regular removal is likely, I use worm drive clamps., But I do sometimes use the Oetiker type on more permanent joints, especially if that was what the manufacturer used in the first place. They're dead easy to remove and install, but I tend not to re-use old ones. Mainly because I either cut them off or bend them all out of shape removing them. I can't be bothered re-shaping old bent and twisted clamps.
I see it as a similar approach as using nails. When you pull a nail, you don't (normally) straighten it out so it can be re-used. New ones only cost pennies.
If I have a job planned where I have to remove some Oetiker clamps, I'll make sure I have a few replacements beforehand. You can buy a special tool to crimp them, but I use a pair of normal pincers. Pincers have sharp cutting edges on them and they only work OK as long as you don't squeeze them like Tarzan and snip the ears right off the clamps.
When doing an un-planned repair, I'll use whatever I have to hand - usually a worm drive clamp.
