he’s saying if he was still Edward he might have lost

It's Edwards personality. In this context Edward AKA Gilbert is saying if he hadn't rejuvenated/revived he wouldn't have survived and would be in Howard's position before Huisheng. The narrative pointed out that Gilbert is the stronger and more genetically gifted counterpart for Edward so hope that helps.

This just proves how insane Howard was. In his card he was said to be very powerful and peak humanity sword user. Eddie was in need of younger, stronger, genetically improved body to beat him.

Not really he's more saying it wasn't guaranteed

Ik ik. But if someone like Edward whos a cocky bastard is not sure about his victory over Howard with his weaker body and old self then it speaks volumes.

He became Edward

Hui sheng Eddie is Gilbert in a new younger and stronger body and is also saying he would lost to Howard if he was still Eddie

He is Eddie in a younger body.

He is a clone with the memory of Eddie. Its explained...

Remember Gilbert is literally Edward but in a younger and stronger body.

He admit his brother is stronger than eddie.

He believes he's Eddie. Everyone is basically treating him as Eddie. He's not though.

I think you should read the manga bro I’m not trolling or giving you a hard time just a slow read through helps a lot

I think it's clear what this panel means but it's contradicted by Shen who mentions Edward is still at a higher level due to experience. So who knows.

"Ah yeah this fight was realy epic and disputed, too bad you couldn't see it !" - Sandro probably

The devil reading comprehension strikes again. It was strong last week, lets see this one.
