buying comics: volume vs issue

So, many people argue on wether to buy comics as volumes (bunch of stories together) or issues (single episodes)
which one do you prefer? both have its cons and pros but which one is the actual best?

Issues are more classic and seem more popular for collectors, but for those who are only interested in reading them, volume would give you more bang for your buck imo. Not sure which is better

i like volumes because they give you proper continuity to the story. sometimes you gotta read a different storyline to keep up example when you read batman between 19 and 20 you might need to read nightwing 10 and when you buy by volume they pile up the story accordingly.

Volumes FTW! Cuz there aren't many issues in my country.
Only spiderman and X man.

I'd rather go volumes. Just seems a lot more organized than individual issues.

I would prefer issues for collector value, but if money is a factor, I would get volumes.
