I have quite a few edge terminated externally polarised dual
diaphragm capsules of various flavours, chinese and otherwise,
including one that may be the same as in your link (though I
haven't tried that one yet).
All the chinese edge terminated LDC capsules mostly tend to being
rather bright, but they also vary a lot between
sellers/manufacturers, while looking almost the same externally.
I'm interested in a single diaphragm large capsule like the 3412
as I haven't got any of those and they may respond differently
from the ones that have a skin both sides, especially in the bass.
As far as frequency response goes a decent 6mm electret is
usually flatter than any chinese LDC - but of course that's not
the only criteria.
The chinese LDCs mostly seem to roll off fairly rapidly below
60hz or even higher.
There's no reason I know of why an electret should be noisier
than an externally polarised capsule if they are the same size.
Since the electret polarisation tends to be more extreme than
usually applied externally they may even work out quieter.

I
hadn't noticed that the 3412? was a 34mm capsule -- my mistake -
sorry about that.
I hadn't thought about trying one. They are more expensive than
the 34mm LDC I'm using at present (
) which I've found to be pretty good.
Those are certainly less noisy, and have a better overall
frequency response than any of the electrets I've tried so far.
