Not easier for me; not easier for the ISP I work for (I'm part of its
collective postmaster).  I, at home, and we, at work, find DNSBLs by
far the lower-cost answer, after all the costs are tallied (dollars
spent, human time, false positives, false negatives, machines, disk
space, network bandwidth, the list of forms costs can take is long).

Perhaps we're atypical.  I've always assumed we're more or less
typical, but just on the general grounds that I assume typicality until
I find evidence to the contrary.
