Consider the following when asking these types of questions. This will work for any item you buy in R/C or elsewhere or topic you have an interest in.

People will have bias one way or the other on every topic or piece of equipment you can buy or talk about. When you ask these questions generally only people whom have a bias will respond. They will either think the equipment or idea is the greatest thing since sliced bread, or it is a piece of junk!

A better way to consider the purchase of an item, is to consider it's market share and the longevity of the manufacturer. Items which are less expensive are that way because they are generally built cheaper, or the company is seriously attempting to capture a larger market share with it's products and giving up some profitability to do so. Built cheaper does not necessarily translate to less quality! It may mean the producer has found good buys on raw materials and/or are paying less for labor.

Also consider the fact that distributors do not like to handle products which do not live up to their customers expectations. If this was the situation with either Supre Tigre or Thunder Tigre, you would not be able to find them, as the companies would have been out of Business along time ago.

In the end what I'm saying is the vast majority of products in a major distributors catalogs are good products! Both the manufacturer's products you have asked about have been around a long time. Like all manufacturers they have had their ups and downs and changes along the way. But, distributors need good products and tend to stay away from bad ones.
