lighthouses are an outside-in tracking system because they use one or more datum point/s to track orientation and position in a given space

the advantages of outside-in tracking is that it works in dark rooms, has better accuracy, slightly lower latency, and less jitter. furthermore, because controllers are independently tracked in the space, they do not need a line of sight to your headset to be tracked. (ask a cuckulus user or WMR user to scratch their own back or rest their head back against their interlaced fingers)

the advantages of inside out is that it requires no external hardware like base stations and it's is usually cheaper because it doesn't require a pile of big sensitive photodiodes, just a handful of cheap russian webcam-tier CMOS cameras, and can theoretically be used for arbitrarily large playspaces
