What do y’all think of this name?

Jennifer

So we just recently found out we are having a boy. Our first son. We thought about baby names even before we had kids.. we have a 3 year old daughter and we had both girl and boy names picked. We like the name Greyson so we have decided on either:

Greyson James OR

Greyson Alexander

Which sounds better or if you have any suggestions they would be appreciated.

Thanks!
