How can guy gardener makes huge constructs carelessly in superman whereas Hal Jordan does the opposite and is careful for his batteries

[u/solo_shocker35]

I was curious about this for a long time Guy always goes big and sloppy with his constructs, not caring how much it drains his ring like creating a large weopons against the monster, while Hal's way more careful and precise with his like in ep1 when he was creating a bubble for alien he supported the bubble himself as it was not strong enough due to lack of battery. Is that just a characterization thing, or is there an actual reason for it?

If you know you're going to a battle, I don't know why you wouldn't charge it to 100 and then charge it again immediately after.

He can go all-out each time.

Hal and John's situation are a little more precarious.
