IME consistency across batches is almost the most important thing. Some brands print better than others, but none is best across all types. I have 3-4 different brands that I have dialed in and trust to perform the same every time and I stick to those. Buying cheap aliexpress filament is a crapshooter every time, even when sticking to the same brand. Sometimes it works well, sometimes it shortens your life by a decade due to frustration.
