On one hand, we have 
, who does too much fucking damage as a support, and mindlessly throws spells all game And doesnt really fall off EVER.
On the other, we have 
, who has annoying af cc which can easily hit you under tower, a pain in the ass to deal with, but atleast she kinda falls off late game.
Neither of them are good enough to waste a ban. Ban 
instead because they're much better in the current meta.
Brand because his CC is faster, and his damage is better.
Personally I ban Rakan because he counters my 
support the hardest but whenever Brand supp gets popular he sometimes steals ban priority.
I myself always go for Brand since he has so muchburst consistently in the bot lane since he can aim for two people. Zyra's plants can at least be killed.
I rather deal with those two than allow this stupid cow into anymore of my games, sadly i can't even do that because im getting sick of having 
and 
in my games.
As a Brand/Zyra player, ban him. Brand will always be strong because of his % health damage in his passive. So even if he's 1/11, he can still 1v9 if your team huddles in his combo and ult.
Zyra can be strong, but she is actually quite easy to deal with. Her plants get oneshot by a melee champion, so even if Zyra get a perfect 4 spitter seed spawn in her ult, they can just be one shot by that Irelia using her Q on them. She's a pain in lane phase, but generally that's about it.
It's up to you though. That's just my recommendation.
Brand >>>>> Zyra
