Verdict

The call

The clearest difference is in-app purchases: Stackd at none against GTO Preflop's 16. Stackd also leads on ads (none vs shown) and update cadence (every 3 days vs every 11 days). GTO Preflop's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 18.0). On price there is nothing between them.
