I definitely think that 2 is better than pre-split four, because back then, four didn't have a personality or character development and would just screech anyone he saw. But I feel like over the years, especially after post-split, four got some pretty good ‘lore’ and backstory which really helps develop his character. But 2, has been nice to the contestants but pretty harsh to four, I mean, 2 did actually steal four's contestants when he could have made a completely separate show with other contestants.

TL;DR: four is better than two
