Depending on your needs, professional use or general amateur use.
The first consideration is size, how much is for personal use
The second is material, single layer or double layer. Generally, single layer is used in hot weather. Generally, double layer is used in cold or rainy weather. Compared with double layer, it has a certain degree of warmth and rainproof performance. The waterproof performance is generally marked on tents, such as 3000mm, 5000mm, etc. Generally, about 3000mm is sufficient, and it is almost resistant to rain.
Then there is the strut. Generally, the relatively strong point of the aluminum pole is selected, and at the same time it must have a certain diameter. I personally think that the diameter of the aluminum pole is at least 7.5mm.
Finally, there are some supporting components, wind ropes, ground nails, etc., which can be selected according to personal needs.
