The performance difference is small, but relates to the integrated base and feet, which provide additional isolation from vibration. The breaker on the 6000/T is rated to 30A (it's set to 20), so the contact area is a small degree less resistive to peak current. These differences could both be qualified as relatively minor in terms of overall performance, so if the form factor or price of the shelf unit is preferable, I would go that route and not worry a bit about missing anything significant performance wise.
