should i use the "if Data" format or the "or" format? (for datastores)

[signal crescent]

--data format
if success and data then
plr.Joins.Value = data.Joins
elseif data == nil then
plr.Joins.Value = 0
end

--or format

plr.Joins.Value = data.Joins or 0

[rustic grove]

Or format behaves like
If data.Joins is nil then 0

So same as before but without success check which would be nice for safety
