For whom it may help, I’ve found that Safari seems—
ahem—snappier and seems to chew through less battery after breaking my years-long use of AdGuard Pro and switching to Wipr which apparently is better optimized and just feels much lighter. Granted blocking may not be as thorough as that to which I was accustomed but so far the trade-off seems quite worth it.
Also, while Adguard filters update seemingly many times a day, Wipr’s only get updated twice a week—meaning I am finally rid of the AdGuard icon on my home screen and the unhealthy habit of compulsively checking for filter updates.
P.S. Reduce motion/reduce transparency/increase contrast/bold text/button shapes/on-off labels FTW
