I mean, Silver Lynel is awesome for farming, some of the greatest materials for weapon attachment particularly the sabers where you get a +55. Plus, it looks badass to put it on your master sword.
One advice I can offer is to try and cheese it with turret build with zionai autobuild with batteries to get the necessary loots from a Lynel. Just simply block it's attack with shield and dodge when able.
I basically did this when I was having trouble killing a silver lynel when my last weapon broke, basically cheesed it with a 12+ laser turret with 3+ big batteries behind it. It eats A LOT of zionites, but damn it's a sight to see the HP melt.
