Blokada has several lists to chose. Some cover social networks, some are specific and some are general purpose. There’s no “best” one, but these are general guidelines:
Start with the default list (Energized Blu)
If it’s blocking too much, go for smaller lists (Energized Spark)
If it’s not blocking enough, go for more comprehensive lists like Energized Basic
Do not select unnecesary lists or several lists, that just uses unnecessary battery and memory
Try other lists too, some lists are small and very effective (like Jerryn’s Goodbye Ads or Steven Black’s list).
Bigger doesn’t mean better!
Energized lists are mutually inclusive so no need to select two of them (example: everything in Blu is included in Basic).
After a little bit of trial select the list/s that fit your needs.
I’ve been corrected by my wonderful colleague @c_C xD
It doesn’t contain the whole of Steven Black unified but some of it.
You can enable combinations of multiple lists to archive more blocking
