Benchmark: String compares (sensitive & insensitive & undefined)

Script Preparation code:

var a = 'aBcD eFgH iJkLmN'
var b = 'AbCd eFgH iJkLmN'
var c = 'aBcD eFgH iJkLmNx'
var d = 'aBcD eFgH iJkLmn'

var enCollator = new Intl.Collator('en', { sensitivity: 'accent' });

Tests:

LowerCase compare a&b
a.toLowerCase() === b.toLowerCase()
Collator compare
enCollator.compare(a, b) === 0
UpperCase compare
a.toUpperCase() === b.toUpperCase()
Sensitive compare
a === b
Lower a & c
a.toLowerCase() === c.toLowerCase()
Lower a & d
a.toLowerCase() === d.toLowerCase()
Undefined test & lower a&b
!!(a && b && a.toLowerCase() === b.toLowerCase())
