What is the tense agreement rule in comparative/subjunctive sentences?


Does tense of the verbs matter in the comparison part of the sentence? As I
understand the main difference should come from the main verb/adjective.

Forexample, in the sentences that are equivalent to English constrictions
_**It would be better...**_ and _**It would have been better...**_ , are all
the past/non-past tense combinations allowed in the comparison below?

  1. 私が話 **す** 方が君が話 **す** より **いい**
  2. 私が話 **した** 方が君が話 **す** より **いい**
  3. 私が話 **す** 方が君が話 **した** より **いい**
  4. 私が話 **す** 方が君が話 **す** より **よかった**
  5. 私が話 **した** 方が君が話 **す** より **よかった**
  6. 私が話 **す** 方が君が話 **した** より **よかった**




  1. As Chocolate says in the comments, it’s better for the より clause to come first, otherwise the sentence feels scrambled/focused and is harder to make judgments about.

  2. In general, it’s best to use the た-form before ほう. The plain form is also technically possible but it gives a sort of categorical reading instead of making a concrete suggestion. See [this answer](https://japanese.stackexchange.com/a/24445/3097) for more on that.

  3. The plain form should be used before より here. The た-form doesn’t feel grammatical here to me because it feels like it’s be referring to the _contents_ of something which happened as opposed to the action (though you see it in unrelated constructions like 思ったより or 予想したより, where the part before より is acting like a nominal referring to what the person thought or expected, and in fact even permits が-の conversion like 彼の想定したより遥かに早かった or whatever)

  4. As for the matrix tense of いい vs よかった, it should simply be whichever tense you want for “would be better” vs “would have been better” (or “should” vs “should have”).
