1-1/8 & 1-1/4 front sway bar vs factory 7/8?

I know most of it is preference but does brand really matter hellwig vs firm feel? I mean they arent too far apart as far as price, also is the 1-1/4 bar even a thought? Or should i just stick with the 1-1/8?

Dennis at firm feel said that since i have the subframe connectors and good shocks the bigger 1-1/4 bar should work good for my setup, whats yalls thoughts?

Thank you all for your help!
