IMHO, the screw connectors hold up better to reuse.
On the few occasions where I have encountered the spring clamp type there always seems to be one or more levers broken off.
On one piece of gear, EVERY lever broke off when I tried to open it.
Of course, this is only what I experienced, on what would be considered a limited sample size. YMMV.
And yes, I have (but very rarely) run into stripped screwheads on the screw clamp type.
Overall it really seems to depend on the application. I can see where the spring clamp would be a better use, especially on stuff that is unlikely to be changed or modified over it's service life (like the specific gear I had encountered.)
But, if something is liable to need to be upgraded or rewired multiple times over its' service life, I think the screw clamp style will hold up better.
And as Harold pointed out, be sure to use the gold plated stuff... especially on audio. I had a problem once with radio signals bleeding over into the audio feed for a remote speaker in a screening room.
I used the HI output, run through a volume control card on the AMX system to a small amp to drive the speaker. After some time, the line level audio connections via Phoenix connectors on the card corroded just enough to make a very effective detector diode. Replacing both connectors with gold plated ones solved the problem, and no callback yet after ten years.
