On size, the Alen 55 is the longer boat at 16.80 m LOA to 16.60 m. It also takes more guests, 20 against 16 on the Alen 55. Drivetrains differ: the Alen 55 runs ips, the Vanquish 55 outboard.
Net of the spec sheet it is a trade: the Alen 55 is the bigger platform, the Vanquish 55 the quicker one. Garage envelope and the missions the boat has to cover should settle it.
