Bing Crosby is the most iconic version, IMO. He actually did several.
If I went with something different, I typically prefer Andy Williams singing most anything.

After Andy I’d go with the one and only Elvis.

Great question!
No one can sing it better than Elvis,
but if you’re looking for just a musical,
upbeat version of Silver Bells, check
out The Ventures. The Ventures Christmas
album is one of my favourites.

Checked my favorite instrumental “Light Jazz Christmas” cds—which usually kept my mom and I from debating over what to play (standards or modern) in the 90’s. Did not have Silver Bells on them unfortunately...
I Heard the Bells on Christmas Day

Had not heard of Echosmith before now, thank you, folks!
Go for the classics:

“WHAT YOU GOT?”
What I “got” for any version of Silver Bells is a trash can. It gets deposited immediately after any version of The Little Drummer Boy.
I’ve always looked for non-traditional variations. I kinda sorta like this one.
