The Weihrauch moderator as been around a long time and set a very high standard,they are also very good value,seen them going for around $70.
The Hugget is a very well made moderator and mite have the edge,the Belita model been very small,so I would think this suits someone better if size is a major factor,the huggets are more expensive,so you must weigh up pro`s and cons for yourself.
The Weihrauch is extremely good value for the money.
