linq-to-sql joins with multiple from clauses syntax vs. traditional join syntax

What the difference between writing a join using 2 from clauses and a where like this:

var SomeQuery = from a in MyDC.Table1
                from b in MyDC.Table2
                where a.SomeCol1 == SomeParameter && a.SomeCol2 === b.SomeCol1

and writing a join using the join operator.

This is for a join on 2 tables but of course, sometimes, we need to join even more tables and we need to combine other from clauses with where if we choose the syntax above.

I know both syntax queries return the same data but I was wondering if there's a performance difference, or another kind of difference, that would conclusively favor one syntax over the other.

Thanks for your suggestions.
