Why Renown is the preferred battlecruiser

Which ship was the best battlecruiser?

Renown, especially after her interwar reconstructions, because she combined battlecruiser performance with unusual adaptability over a long service life.

Renown is the preferred choice when the comparison is limited to ships designed and used as battlecruisers. Repeated reconstruction kept the ship useful as weapons, sensors, protection, and fleet needs changed. That adaptable service history matters more to this judgment than simply selecting the largest or most heavily armed design. The choice remains personal, with reconstruction providing the practical reason behind it.
