The volume vs quality trade-off
HeadshotPro's thing is volume: upload 10+ selfies and get 40 headshots in different outfits, poses, and backgrounds. For a corporate team that needs headshots for 50 employees, this is genuinely useful. But for an individual who just needs one good LinkedIn photo, 40 variations is overkill — you'll use one, maybe two. TrendAvatar's simpler approach (upload one selfie, get one polished headshot) is better suited for individual use.
