Probably gonna get a few different opinions here.
Personally, i think your tops are shaping up really nice. I'd be more concerned about scraggily crap underneath the canopy. The ones that branch off and don't amount to much at all.
I'd generally leave the leaves on, even the lower fan leaves, where you take spindly branches away. It's stored energy the plant can use later on, and can aid the plant if there's a nutrient deficiency etc further down the road.
Keep it simple, plant looks great.
