It definitely comes down to what you prefer. I mean Jeremy Jahns and his style in his videos feel very representative of where society has gone, the "ADHD-generation" where everyone want their information as short and easy to digest as possible, so you get a 4 minute review which is very fast paced, fast edits and it basically gives you the points right away. Nostalgia Critic is more theatrical with sketches and more suited for people who enjoy that, and RLM is 30-60 minute reviews (not counting the plinkett ones which are longer) where it's more about talking about a movie (like friends do) rather than "these are the positives, these are the negatives, here's the grade.. BYE".
I can see valid points in all type of reviews and get why someone would prefer A over B, personally I enjoy the slow analyze of RLM over a fast paced 4 minute review, but that's me. But I also find it interesting how certain reviewers, like Stuckmann and Jahns can do similar things (their reviews are often around the same length), yet I always feel like Stuckmann takes his time and lays out his points rather than speeding through it, like Jahns. So even though on the surface it looks like they are fairly similar, I really love Stuckmann but don't care much for Jahns. (but like pointed out earlier, put Jahns in a panel or something and he becomes good IMO)
