Verdict

The call

The clearest difference is price: Z at Free against Groundskeeper2's $3.99. Z also leads on rating (5.0 vs 4.3) and review sentiment (100% vs 69%). Groundskeeper2's advantage is ads (none vs shown) and ratings volume (19 vs 2). On update cadence, in-app purchases and device support there is nothing between them.
