それに関しては賛否両論あるよね。

for 〜 で「〜に[賛成](https://eikaiwa.dmm.com/uknow/questions/45416/)」、against 〜 で「〜に反対」と言えます。
祐希さんの言う通り pros and cons もとてもよく使う表現なので、お好きな方の表現を使うと良いと思います〜！
There are two sides to this argument, for and against.
The example states that the argument has a positive and negative side.
By claiming that there are two sides, you are essentially stating that there is an opposite view in the argument.
An argument for implies you agree with it, an argument against, states you disagree against the argument.
pro's - pro literally means for, so a "pro" is a positive
con's - con literally means against, so a "con" is a negative
upsides - to be up is to be on top, so an upside is a positive
downsides - to be down means to be underneath, so a downside is a negative
Advantage - a favourable or desirable feature
Disadvantage - an unfavourable circumstance or condition that reduces the chances of success or effectiveness
