rli2 is definitely faster - once you've paid the initial cost of the sorting of the input files first. but it only takes one file to be removed as input.
there's also a new project 'rling' in progress (https://github.com/Cynosureprime/rling) that has some knobs to customize trade-offs. it's already useful, but still actively being debugged and modified, so YMMV, and support for it is probably off-topic here.
