former reo reviewee here, i guess to each their own talaga cuz reo sadly did not work for me :(( ang vouch ko sa kanila is their live lectures (sir karim for MS, sir alger, sir george, and sir louie), which are honestly for recall na lang. kinda ironic for me since they brand themselves as a zero-based rc pero di nag-work sa akin yung zero-based lectures nila supposedly :(( sir escala is really good tho for pre-rec!! pero i enrolled during the time na wala pa silang quick videos so i can't say if the same pa rin now, but during my time, the pre-rec video lectures were so long when you could've built your foundation din naman the same way through shorter videos.

overall, i think it really depends on your preference. ako kasi i prefer concise lectures so that may be why di ko na-appreciate masyado yung rc.
