We wouldn’t say any of them is better or greater, because it depends. This one may be better than the other on a surface but worse on another surface.
Let’s just look at the pros and cons of each one.
The brush is widely opted by the professionals, because it does well in retaining the paint on the bristle part. What’s more, thanks to its comparative control, cutting into sockets, door knobs or tight corners is too easy to be true.
As for the pad edger, you may oftentimes make a mistake by applying too much paint on. But if used properly, the pad edger can make well clean lines and thus save you lots of times.
Hence we suggest you keep both a brush and a pad edger for your cutting/trimming works.
