Unique boy names S

So hubby and I have been talking about names for months. I like simple names so people can understand and write them easily like school etc. my hubby wants unique names to stand out but I think kids might pick on him if name is really different. We have a son named Skylir and its little different but not too crazy-took six months to agree pretty much. 

Names we are thinking of begin with S 

Samuel

Sawyer

Slade 

Saveri 

Silas 

Any other ideas for simple but unique name? I've looked online forever too.. Thanks!
