The considered comparison
Duke & Bluecrop
An early bowl, or a midseason staple?

The short answer
An early bowl, or a midseason staple?
Start with harvest timing. Duke is the earlier choice in the cited Pacific Northwest guidance; Bluecrop is the midseason one. Both are full-size, high-chill northern plants.
Editorial interpretation of the linked specifications, not a firsthand head-to-head trial.
Consider Duke when
An earlier harvest.
You want to investigate an earlier picking window and have a well-drained site with enough space for its listed spread.
Consider Bluecrop when
A midseason staple.
You prefer a midseason crop and the narrower mature spread in the nursery listing suits the planting bed.
The evidence behind the choice
What the specifications leave out.
Duke
Beyond the nursery listing
Early fruit is not early bloom
Santa Clara observers describe early harvesting despite later spring bloom. Read the evidence ↗
For your decision. Keep the harvest plan separate from the pollenizer question. Ask about local flowering overlap.
Santa Clara County, California. Local observations, not a national performance or chill guarantee.

Ripeness changes the comparison
OSU notes tartness when fruit is picked early or bushes overcrop. Read the evidence ↗
For your decision. A nursery flavor adjective cannot tell you how an overloaded bush will taste. Plan for pruning and fully ripe picking.

The tradeoff to keep in view.
Do not confuse early fruit with early flowering. The harvest comparison does not establish pollination overlap. Also, Duke’s documented drainage sensitivity makes the planting site a more important constraint than a small difference in fruit description.
Before you choose.
Confirm local ripening order, drainage and a compatible bloom window. If both fit, choose the picking season you actually want.
