Which is better for a 3-acre lawn?

Either handles it; the ZT2 54 is rated to 5 acres and the Z2 50S to 2 to 4. The wider 54-inch deck also finishes a 3-acre lawn faster.

Is the ZT2 54 worth it over the Z2 50S?

Yes for most buyers. It is cheaper at the listed prices, cuts wider, and has more height settings. The Z2 50S only wins if you need cruise control or the light bar.

Which has the better transmission?

The ZT2 54 names a Tuff Torq TZ 350 hydrostatic unit, a common serviceable transmission. The Z2 50S listing does not name its transmission, so it is harder to compare.

Can I mulch with either mower?

The ZT2 54 mulches with a separately sold mulch kit. The Z2 50S listing does not state a mulch option, so confirm with the dealer before buying.

Which is easier to store?

The Z2 50S has the narrower 50-inch deck, which helps with gates and shed doors. The ZT2 54 is 65 inches wide overall and weighs 1,424 lbs assembled.

Do both use the same engine?

Both are 23 HP gas V-twin engines. The ZT2 54 lists 726 cc displacement; the Z2 50S specifies the Kawasaki FR Series.
