Boba lead or move to Rex lead?

Recently got under top 125 in my shard ( it sure ain't top 10 , but i got to top 125 on a november shard after quitting for 3 months then coming back)

I've currently been rocking the
Boba (L)
Wedge
Biggs
Rex
QGJ

now, i've been to the point where i'm facing some zaul/zader/zqgj teams so I've been told to try out a rex lead, but the problem there is i hardly score critical hits with my team and it feels like im barely making a dent
My tema is missing a taunter so im currently working on getting Sun Fac up ( can't get baze cause im not near the hard node yet)

But any thoughts on how to improve my team? (certainly not meta but it gets the job done sometimes :)

Thank you All!
