I much prefer compression fittings personally
Never had one leak , Barbs and Clamps can cause hoses to split if too tight.
Compression fittings are easier to use in tight spaces or angles where you cannot tighten a clamp
Tubing doesn't get hot, and certainly not hot enough to alter the composition of the tubing to cause wear or cracks. If tubing goes bad it's typically due to UV exposure or over-tightening of fittings or components.
I also use barbs- cheaper and work just as well. Like 4ryan6 mentioned, they are well suited for good looks in a case, but they are actually just specialized barbs with a screw down ring for securing the tubing vs. using a clamp of some sort.
