(Spoilers Main) Characters with the most underrated fighting feats

Which characters you believe receive less recognition for their martial feats than they should've?

My top three is Ulmer of the Kingswood, Sandoq the Shadow and Ser Tygett Lannister.

Ulmer was part of the Kingswood Brotherhood, and claims to have put an arrow through the hand of Ser Gerold Hightower, the Lord Commander of the Kingsguard and stolen a kiss from Princess Elia. There's no way to confirm the veracity of these claims but Ulmer is shown to be skilled enough to be a ranger for the Night's Watch and was entrusted by Jon to train the recruits with the bow, making him one of the best marksmen of the Watch at least.

Sandoq is probably the best fighter of the trio but is also the one who received the most acclaim for his deeds as a Kingsguard. He defended the then King Aegon III and the future Viserys II during the Lysene spring, slaying a Peake and a dozen soldier by himself.

Finally, Ser Tygett gets overshadowed by Tywin and the fact he died before the start of the books, but was a menace when alive. He squired in the War of the Ninepenny Kings, killing a man in his first battle. He was just ten at the time. He killed three more men, including a knight of the Golden Company. He should've earned knighthood on that alone, but was refused simply because of his age. He was refused a great battle as an adult but one could only wonder what he would've done if Tywin sent his forces to the Trident.
