Revive old channel or rebrand new channel?

I have an old channel called azvn. It's a stylised version of my name, I have memorable handles on all platforms. It was a gaming faceless channel but I really like the branding because I'm going to become a personality channel anyways. It's about 4 years old. 1k subs. Also have a tiktok at 8k followers and 100k+ likes.

My new channel, 70 subs, I started uploading daily shorts from a week ago (all around 1k views) and one long form (also 1k views in a few days). Called fourleafnova. I like it but would rather be called azvn. The content will be stuff like discord call clips, reacting to news, social media posts, might include gaming etc (not all sporadic, I'll focus on parts at a time of course) but in general it revolves around ME and my reactions, takes, etc. Hence the rebrand.

Now do I change the handles of my new accounts? Or revive the old accounts? On the one hand I get more subs and therefore social proof. On the other hand the algorithm might get confused since it isn't the same niche. I've heard both sides of the argument about the algorithm, I'm confused what to do
