Variant notes
- から言えば — the ば conditional in place of と — stiffer and more written, at home in reports and argument; から言うと is the safer spoken default.
- から言って — the clipped て-form (結論から言って, 経験から言って) — drops the conditional's "if you go by this" framing and states the judgment as following directly.
Notes
works, but a person's own side needs にしたら or にとって. The one frame that does
take a person is the causative 私から言わせれば.

The two take different nouns — からいうと takes the ANGLE a verdict is delivered from (結論から言えば, 値段から言えば) and its tail is the speaker's own evaluation, while からすると takes the EVIDENCE an inference rests on (この様子からすると, あの口ぶりからすると) and its tail normally carries a conjectural marker; the idiom 結論から言うと "to state the conclusion first" has no からすると twin, since 結論からすると can only mean "judging from the conclusion someone reached".
にとって names the party a judgment lands on and takes a stative predicate (学生にとって高い "expensive for a student"); からいうと names the scale the judgment is measured by (値段から言うと高い "in terms of price, it's expensive") and resists a person noun altogether, so neither frame substitutes for the other.
からいうと picks a criterion and delivers the speaker's own verdict by it (安全面から言えば問題がある); の上では reports what a record, a figure or a formula says while withholding the speaker's agreement (計算の上では間に合う) — からいうと carries no "…but really" undertow, which is the whole point of の上では.
Lookalikes
One particle apart — 日本と言えば／日本から言えば — and both open with 言う, but と言えば picks up a noun just mentioned and free-associates from it ("speaking of Japan…"), while から言えば makes that noun the scale a verdict is measured on ("in terms of Japan…"); と言えば never supplies a criterion, and から言えば never introduces a topic.
