Worst this approach worth the hype? [v5]

The trade-offs here are not obvious to me and I keep flip-flopping. Been thinking about this for a while and curious what the community thinks. Not sure if this is the right place to ask, mods please remove if it is not.

Quick context: I am relatively new to this and trying to find my footing. Long-time lurker, first-time poster. Spent the last few weekends digging into this and the deeper I go the more questions I have.
