Chains of binding or hungry fangs for sekhemas final boss?

I’m almost at the last room and I only have these two options. Which would be least painful for the fight. I’m currently at 77% movement speed. Ignore the fact that I also have deceptive mirror which means I don’t always go to the room I pick.

Always binding hit, one of the weakest debuffs
100% go chains. if you get caught in the boss multihit lighting thing with the -5% hp on hit its very risky
Both are on hit effects. On top of that, you have deceptive mirrors. It's 50/50 anyway. Just watch the boss mechanics video if you haven't.
You got this, op. Try to skip the movement slow one as the boss has me mechanics that requires movement speed.
Chains r ez
If it helps, the bottom left corner is nearly not touched by the rotating beams.
You should have also posted the build you're playing for the best advice, but according to my experience, these two are both meh regardless. Especially since you have the 'not always taken to the room you select' affliction, it really doesn't matter much. I'd just look at which room has the best price and pick that.
The 5% one killed my character so fast during his whirlwind ability
