Is there any difference between 早く終われば and 早く終わったら?


Consider the following two sentences,

  1. 仕{し}事{ごと}が早{はや}く終{お}わったら行きます。
  2. 仕{し}事{ごと}が早{はや}く終{お}われば行きます。

Is there any difference between them?




There are few chances you could sense the difference outside some edge cases
but, yes, they have a little difference such as...

`AたらB` literally comes from "When A is over, then B", so it could imply that A
has higher probability to be satisfied. `A(れ)ばB`, on the other hand, doesn't
get along with an A happens as matter of course.

> 明日起き **たら** 電話します。 (Fine.)
>
> 明日起き **れば** 電話します。 (Won't you get up tomorrow!?)

`AたらB` can describe a one-off event, where `AればB` indicates general condition.

> 天国に行っ **たら** 何をしますか？ (Fine.)
>
> 天国に行 **けば** 何をしますか？ (Are you going to heaven every vacation!?)

(Note: judgements may vary among speakers, see the discussion below.)

As an aside, `たら` is not formal language. You should use `-たならば` in those
settings.
