It really depends on your preferences and needs. TOP LOADER: The top loader might be better if you're looking for a dispenser with more features. These dispensers often have more options for customization than bottom loaders. The dispenser has an integrated reservoir that can hold more water, making it easier to refill. Additionally, the spout is positioned closer to the mouth, which makes drinking easier. BOTTOM LOADER: If you're just looking for simplicity and convenience, then the bottom loader may be what you need. This dispenser has no built-in reservoirs; users must fill it from time to time using their own bottle or cup (which is often less convenient). However, there are some disadvantages to using a bottom loader. One problem is that they tend to be less stylish than toploaders. Another issue is that they can sometimes become clogged due to sediment build-up over time.
