Vedalo HDs for me; no question.
Loved my Serengetis but they fell apart twice in normal use; The first time I paid the ~$170 to get them repaired, but when they fell apart again just 3 months later, I put them back on the shelf, where they remain broken and unused. The cost of ownership matters more than the cost of initial purchase.
Everyone will vote for whatever they currently use, but the HDs are brilliant; including that the colour is built into the lens not layered on, the side arms are really thin & flexible for sitting under headsets, and when I needed a new nose pad they posted me half-a-dozen from the US with no delay, debate or cost.
