Pat wings dry with paper towels; lightly season with salt and pepper.
Whisk Buffalo sauce, melted butter, honey, Worcestershire, garlic powder, and paprika in medium bowl.
Toss wings with sauce in slow cooker to coat evenly.
Cover; cook on low 3-4 hours or high 2-2.5 hours until tender and cooked through.
For optional crispness, transfer cooked wings to sheet; broil 3-5 minutes, watching to prevent burning.
Return to cooker; toss in remaining sauce. Serve hot with ranch or blue cheese dressing and celery.
