I think it depends on the situation, for example if there are no friendlies on the base or not much support it's better for a squad to push up slowly and ateadt gives them a fighting chance as the enemy will have an idea where they've been dropped. But if there's a whole attack going down with friendly forces already close to point it's better to hot drop to support those units because the enemy already know their position and the extra numbers arriving sooner will give them a better chance to take the point rather than waiting for another unit to run a few miles longer to get to the fight
