Can someone please tell me which pronunciation is more common? Thanks!

Or I should've said "เหลอ" and "หลอ" (the pronunciation not the spelling)

it should be เหรอ not เหลอ,

because เหลอ it not exist.

หรอ not หลอ

หลอ is common use as slang or intend to mistype by teenager.

หลอ usually use with ฟันหลอ = broken tooth

Is this question about the particle at the end of certain kinds of sentences?

If so, though written หรอ it's usually pronounced รึ and written as such in things like film subtitles.

หรอ is informal, not use for writing or in text book.

เหรอ is more common to use.

fyi,

Q: วันนี้ ไม่ไปไหนหรอ, วันนี้ไม่ไปไหนเหรอ , วันนี้ไม่ไปไหนรึ = don't you go anywhere today?

A: ทำไมหรอ, ทำไมเหรอ , ทำไมรึ = why?

it's exactly the same meaning, doesn't matter how you pronounce it's all the same. but เหรอ is more common

In addition Thai people enjoy to use their words or pronounce in different way to make sentences more emotional and tease with those word.

Such หรอ , nowadays it's most likely to use หรา among teenager หราาาาาาาา very informal to use and parents hate it, it's kind of mocking more than questioning.

sorry for my bad English, i'm Thai feel free to ask

That's why I said that I was talking about the pronunciation not the spelling. In colloquial Thai, the ร is pronounced as ล.

หรอ is informal, not use for writing or in text book.

เหรอ is more common to use.
