Yes — Lightroom and Aperture both support basic Photoshop round-tripping, so your adjustments are not simply lost when sending an image to Photoshop. In general, edits made in either app remain part of that app’s non-destructive workflow, while Photoshop edits are saved separately in a rendered file.

Lightroom’s main integration advantage is that it shares Adobe’s RAW processing engine with Photoshop/Camera Raw. That can make RAW rendering and handoff more consistent between the two applications.

Lightroom also offers tighter Photoshop workflow features, including one-click handoff for multi-image tasks and options such as merge to panorama, merge to HDR, layers-related workflows, and opening as a Smart Object in Photoshop.

So if your question is strictly about Photoshop integration, Lightroom does have some advantages over Aperture. If you’re already happy with Aperture for organizing and standard edits, the biggest reasons to switch would be those Adobe-specific integration features and the shared RAW engine — not necessarily a dramatic difference in basic library/editing capability.
