This is actually a really good fight. I slightly favor Whyte because of activity but wouldn't be surprised if Browne won.
I hope Browne will beat Whyte. Whyte is hyped by Hearn whereas he's nothing special and never had any tools to be an elite fighter. But sometimes a fight between two average fighters turns into a great war and this fight can be the case. Of course it can be boring as **** too if Whyte won't take risks and tries to 'outbox' Browne (means doing nothing but try to jab and run away).
Browne right after Chagaev would have been a true 50/50 for me. But I favor Whyte not, Browne has been inactive. He's only fought 3 times since 2015. I don't think Whyte will take risks because he doesn't have good power. Browne would stop him if he went to war. I'm not expecting an amazing fight but I just love 50/50 type match ups even if they have the potential to be stinkers.
