It really depends on your preference:

Cold press paper has a slightly textured surface. It is the paper used most often by watercolour artists because it's good for both not only large areas of wash but also for a good amount of detail. Also, the textured paper allows to shape things easier!

Hot press paper has a fine-grained, smooth surface, with almost no tooth. It's ideal for large, even washes of one or two colors, drawing with pens and ink wash, and for painting fine details. The smooth surface makes it easier to draw and shade with dry mediums.

The best paper is acid-free and has a high amount of cotton because it means the paper won’t turn yellow or deteriorate over time.

Also, the more cotton a paper has, the better it holds water and keeps the pigment much more vibrant.

Yes, it does! Don't worry, you can definitely use both sides of one sheet of paper - that's how good the paper is!
