Performance separates these two: the Wally 50X tops out at 54 knots against the Alen 55's 35.
On size, the Alen 55 is the longer boat at 16.80 m LOA to 15.40 m. It also takes more guests, 16 against 12 on the Wally 50X. Drivetrains differ: the Alen 55 runs ips, the Wally 50X outboard.
Net of the spec sheet it is a trade: the Alen 55 is the bigger, higher-capacity platform, the Wally 50X the quicker one. Garage envelope and the missions the boat has to cover should settle it.
