Very nice explanation!using the default settings in both, adguard beats ublock because adguard's english, spyware and annoyance filters are much much better than ublock's basic filters combine
ublock with these adguard's lists + other great filters >>>>> adguard
adguard can't add custom filters and manage/autoupdate. When a filter is added into adguard, it is copied and pasted (automatically) into user filters -> when you want to update the filter, you must redo the above step, manually => that's why I hate adguard extension
1 more thing, adguard isn't fully compatible with filters made for adblock plus and ublock. When you copy some rules into adguard user filter, adguard will show syntax error
@TerrakionSmash - I don't know how you normally use uBO or Nano, but if you use either in Advanced user medium mode you can do away with some default filters. Then speed is no problem at all. But this depends on your browsing style. If I wanted only an adblocker in Edge I would use AdBlock.
