The review process at the "prestige" journals in many disciplines is garbage. This is a known issue. Competent experts simply don't have time to do the reviews, so they end up being farmed out to graduate students and post-docs if they get done at all. I had one paper get rejected, because they couldn't find anyone to review it! By the time a reviewer is found, you're often the action-editor's last desperate pool of 5th-tier people who are sort of maybe vaguely related to the topic area.
Add to that that the majority of papers in many disciplines receive virtually zero statistical oversight from an actual statistical expert, and... well... you begin to wonder what service the existing journals are actually adding. Marketing and sales?
