Should I buy a corded pillow-style massager or a cordless wearable?

Corded shiatsu pillows (Nekteck, Zyllion, Mo Cuishle) draw the largest verified-purchase histories and tend to deliver stronger, more consistent kneading because they aren't battery-limited. Cordless and wearable models (Bob and Brad iNeck, the 4D wireless unit) trade some power for hands-free use at a desk or while traveling. Pick corded for at-home depth and cordless for portability.
