php handler DSO vs suPHP

I am having troubles updating my server and they say that DSO is something they avoid using. I guess I had it installed when I was working on the caching of my app.

My question is which handler is better ?

Better as defined in faster, safer and more standard (easier in support)

I read that DSO is faster and can do opcaching (whatever it is … is yii2 using that in his caching ?)

and that suphp is safer… and permissions easier to update

What do you recommend and why for running yii2?

looking forward to your experise

I am running php7
