This is largely a trade-off between visibility and light protection, and both are legitimate depending on the priority.
Glass doors let the collection be seen without opening it
A glass-door cooler lets you check on stock and show off a collection without opening the door and disturbing the internal temperature — see our note on UV glass for the light-exposure consideration this brings.
Solid doors block light entirely
A solid door removes any light exposure concern completely, at the cost of not being able to see bottles without opening the cabinet.
UV-filtering glass narrows the gap between the two
Many glass-door coolers use UV-filtering glass specifically to reduce the light-exposure downside while keeping the visibility upside — check whether a specific glass-door model states this feature.
What to check before buying
If display and easy visual stock-checking matter, a glass door (ideally UV-filtering) is the better fit. If the unit will sit somewhere with regular light exposure and visibility isn’t a priority, a solid door removes the concern entirely.
What we would not do
Suggest a plain, non-UV glass door is equivalent to a solid door for light protection — that’s specifically what UV-filtering glass is meant to address.
