I no longer own a Guthans set, Bandos is better for me because I no longer need to heal on task with a Bunyip and +330 melee defence. I still own Veracs for TBird tasks and Karils for some other, but otherwise Guthans has become obselete for me.

Barrows, I rather be a total defence noob than being a guy who will rather have a higher strength bonus to sacrifice is defence...

I'd go with bandos, good str bonus , and the def bonus isn't THAT bad...well...

barrows is better in def but i hate repairing it

 

i prefer using my bandos armor then barrows
