Which download tool do you use? Thunder or Internet Express

Download tool is one of the most widely used network tools. Because of information sharing, the large-capacity information sharing and transmission cannot be separated from the existence of this network transmission acceleration tool, many download tools are commonly used: "Internet Express" and "Thunder". Thanks to its advertisement and domestic software, Thunder has been gaining popularity in recent years and began to watch its students use thunder, after working, I watched my colleagues use thunder, so I was curious. I also downloaded thunder to enjoy her extreme enjoyment, of course, I still need to use my old friend "Internet Express" before enjoying it. (when talking about Internet Express, I don't know it was used that year, but I still use it in IE and Firefox ), when I started using "Thunder", I chose the links that recommended using thunder. It felt a little slow, but I didn't care! Today, I have thoroughly understood the true nature of Thunder:
Specific data is as follows:
Thunder: 432 M 45.3%
Internet Express: 280 m 60%
250 m 100%

The above links are all from the Microsoft website. The 530 M data is downloaded at the same time by the Internet Express. The difference between these links makes me stunned. In the end, the speed of thunder slows down and makes me impatient, I would like to ask if you have enjoyed the advantages of thunder when using thunder. If not, please give up or give up after comparison!
However, in Firefox, Thunder can be used without installing plug-ins ........
