Question about Creality Ender 3 Pro

Take the Ender 3 Pro if you want to buy one of the two, this is the slightly improved version of the Ender 3.

and in terms of print resolution. Even though the Pro should be able to do 0.05mm, you will rarely use that and 0.01. I print most of my stuff in 0.2mm. For most things this is enough. Unless you really want to print small but very fine/detailed things. The finer something is the longer it takes to print. And depending on the size of the object, the printing time can be several hours. With larger objects and <0.2 also well >10h.
