High bridge atomizers are designed for cartridges (which few use) and some are designed for cheap rebrander cartridges that come sealed with a foil end instead of having a reusable silicone plug (the high pointy bridge is needed to pole
through the foil).
Most vapers do not use cartridges and use cartomizers instead for everyday
vaping. And atomizers can be used on a sealed manual battery w/ a drip tip for testing juices or
vaping occasional juices at home. For dripping the low bridge usually preferable to high. And re the suggestions above - some use wickless or bridgeless atomizers for dripping but those cannot be used with cartridges.
