IMHO, weighted action is only useful when you’re playing stuff written for piano or harpsichord.
Jokes aside, I have the same answer for both of these polls… Depends on the job.
I have to say I prefer synth weighting, simply because i’m not really a pianist.
I find that the weighting slows me down, so I like really short travel keys with a light touch. Hammond’s are the schitz for me personally, though my DX27 has a really really light touch which is nice. Just a bit too much travel.
