Which is better to read?

file.js

// For context, we have two arrays of routes (['get', '/', ...], ['put', '/:id', ...]) that we are checking for collisions
// Then removing the collisions from the base array (actions)

// #1
// Remove conflicting routes by filtering out items from the base actions where the first 2 values are equal.  Coerce the result of find() to a boolean.
actions = actions.filter(a => !actions2.find(a2 => a[0].toLowerCase() === a2[0].toLowerCase() && a[1].toLowerCase() === a2[1].toLowerCase()));

// #2
actions = actions.filter(a => {
    // Search the new actions for a case insensitive match.  Coerce the result to boolean, and return the inverse.
    return !actions2.find(a2 => a[0].toLowerCase() === a2[0].toLowerCase() && a[1].toLowerCase() === a2[1].toLowerCase())
});

// #3 ?
