Hi,
It’s not like Fiat vs. Mercedes, but rather like drinking wine (or beer) from plastic goblet vs. a glass.
The content is the same wine (or beer) and you can have fun with both;
It depends on the circumstances and personal expectations.
The plastic goblet is fitting well to the purpose of capturing a liquid in order to drink.
The glass is doing the same, but it’s often more appropriate for developing flavor and tasting. You will be able to discover the character of your beer (or wine) much better with a glass, because it’s developed for that.
The plastic goblet is the simplicity and without any feature, a real lover of wine (or beer) wouldn’t really care in case of thirst. As we say in France, the best wine is the one you have in hand.
Both can be used in garden or on a picknick.
And yes, both have a market, but finally don’t cost the same.
Cheers
