I like the first hand.

The second hand... There're way too many people behind you. You can afford to wait. Especially when it's still 8 handed. Level 4 doesn't mean you get to start pushing all over the place. The number of players also matter. 6-7 handed and MP, I'll push that. With 8 people and UTG, I'd probably muck it. Don't even bother limping because a LP will probably steal it from you.
