Other Are spigen cases worth it ?

Protection wise I doubt an expensive case is much better.

I would only go with them if you like the design and appreciate the quality in your hand.
I'm partial to UAG's ice series cases. For some reason their PC cases with Tpu sides are quite grippy. Well made, look great and protect well

They didn't do one for the S20FE so I found a generic that was a dead ringer. Just as good as the last one I linked and less than 500
 
Been using Spigen for years, last two phones before had Spigen, dropped many times no damage whatsoever.

Switched to UAG Armour on my new S25 Ultra, very good case one of the best you can buy really, but five times the price.
