No, they are the same.

Both will extend the buffer when the runtime can guarantee it is 
allowed to, which it quite often can. Details here:

I recommend just trying it with ~= (avoid a ~ b though, a ~= b is 
better when possible) and see how it performs before getting too 
worried about it, the built in really isn't bad.
