Which sentence is best in english ?
Context: I'm asking a question to a friend about what I should take with me for my next holiday.
The way you have your questions written is actually a little bit wrong and not natural at all. But I can think of two possible ways to phrase this type of question:
1:
Do you recommend I take warm clothes with me?
or
Do you recommend that I take warm clothes with me?
2:
Would you recommend taking warm clothes with me?
The grammatical patterns of the two sentences are as follows:
do you recommend (that) I do something? (recommend (that) someone do something)
would you recommend doing something? (recommend doing something)
A bunch of other examples:
Example #1 (pattern #1):
I recommend you go and see the dentist right now or it might be too late and you will lose your tooth.
Example #2 (pattern #1):
I recommend she call her parents right now or she'll be in real trouble!
Example #3 (pattern #2):
I would recommend watching the explanation video first because that way you will get the understanding down first and be ready to tackle the exercises.
Example #4 (pattern #2)
— Which hat would you recommend buying?
— I'd buy this one.
P.S.
You might be wondering why in pattern #1 the second verb doesn't end in s. That's called the subjunctive. Subjunctive structures in English do not require that. They always go with bare infinitives. recommend is one of those verbs that almost always intrinsically has that subjunctive sense to it.
As for the question, this is how I personally would say it:
Do you think I should take warm clothes with me?
