Verdict
The clearest difference is rating: 66 Challenge at 5.0 against TripleWhale's 2.7. 66 Challenge also leads on update cadence (every 5 days vs fortnightly) and iOS requirement (13.0 vs 16.4). TripleWhale's advantage is in-app purchases (none vs 3) and ratings volume (38 vs 5). On price, ads and device support there is nothing between them.
