Compression Fittings vs Straight Barbs?

[MrToad]

Neither... Push-in fittings FTW

Of course, you're limited to 12/9 tubing (unless you want to use a lot of 3/8 > 1/4 adaptors), and it takes a bit of ingenuity if you want to use rigid tubing.

On the upside, no plasticizer leech if your use PU (or even copper) and no other solution comes even close in ease of use

And, of course depending on taste, some even look good 'n all

Not the ones I use though, but they're cheap and cheerful and once I close the case I don't see them
