As people have mentioned, it is purely down to why/what makes you do Youtube. The perfect scenario is you can combine the two, however, that is not always possible. If you purely did the hot topics and latest trends, would you enjoy it as much as when you do videos you enjoy? if the answer is yes then great... if it is a no then it may start to reflect in your content (not that into it, less effort)
I personally try and do both, but I don't force it, if it doesn't work for me I don't do it. I know when I make videos purely for the clickbait the videos aren't as funny and I don't put that extra effort into making it funny or 'perfect' because my heart isn't in it.
Something to think about, if you are energetic, fun, interesting, and relatable, people will watch your videos regardless, yes you may not get the massive CPM that comes with a clickbait video but you will organically grow a following.
