White Fire - Two phenotypes

A couple of old WiFi seeds I found from a few years back I gave to a buddy. They are about 2 months into veg. I told him to top them or train but he didn't listen.
 
can you explain why you guys like topping it? so it grows in a V?

i like just keeping it natural
I feel you on leaving em natural bro, but IMHO topping is essential when growing indoors to promote an even canopy of tops, equaling more buds at the point of the greatest lumen concentration and giving you maximum yields!!
Some to it because of space issues as well, in high humidity scenarios too, you might not want one giant sized cola...many smaller nugs may be better when mold maybe a concern.
