meaning of で言っても?


Found this sentence:

> 人生経験で言っても、十数年引きこもっていた俺よりも、彼の方が上なんだろう。

Is it a grammatical structure or am I missing something?




This で言っても can be understood as

  * で : which aspect is being talked about. [基準を表す](https://dictionary.goo.ne.jp/word/%E3%81%A7/#jn-148951)
  * 言って : te/continuative form (but see note)
  * も : also

Combined, _also speaking in terms of hands-on/real life experience_...

An implication is that _he_ is superior to the speaker in some other terms.

**Notes**

Removing も= _also_ would give 人生経験で言って, which is a bit unnatural. で言うと will be
more usual. I don't have a good explanation for this.

ても in と言っても is independently covered in grammar (e.g.
[this](https://jlptsensei.com/learn-japanese-
grammar/%E3%81%A8%E3%81%84%E3%81%A3%E3%81%A6%E3%82%82-to-ittemo-meaning/)) and
is used for connecting contrary-ish clauses.
