Sabre ultralight vs inox lames at similar price points

Hi, I am looking for a new Sabre lame and I am kind of looking between the PBT INOX lame for $145 or this BG lightweight lame alternatively I have a coach and mate in China who has used this lame for $122 which he says is pretty good and hasn’t had a problem in last 2 years of using.

Which one might be better for me? I have only fenced for around 2 years but I’ve started going to higher level competitions than just my local and regional comps.

I’m particularly concerned with the durability and anti oxidative properties of the lames but I’m also interested in the light weight aspect (I really enjoy my super light whites over the old heavy ones)
