I've always had an interest in how the hero looks. Be interesting to see which you prefer. See where there's consensus and disagreements. Here's mine:
The Batman (2022). My favourite live action Batsuit.
Batman Begins (2005).
Batman (1989). Batman Returns (1992) looks better but I have more emotional attachment to this suit.
No The Dark Knight (2008)/The Dark Knight Rises (2012) as the suit is too busy and the Bat symbol is way too small. Batman v Superman: Dawn of Justice (2016) is too bloated. I prefer the test suit.
