「〜といいます」 vs 「〜というものです」 when introducing oneself


When introducing one's name, I have seen both of the following constructs
used.

> 〜 **といいます** 。
>
> 〜 **というものです** 。

Is there a difference between them? I get the hunch that the latter is perhaps
more formal than the former, but just how formal is it?




No difference. Both of them are polite or formal.
