Personal brand username or SEO username?

So glad I just found out this subforum. I'm really looking into the insta marketing game and I've got a question about usernames. I'm just trying to grow my personal account, but I see a lot of insta marketing guides saying you need a recognisable username. So what do you guys advice for a personal account? Keep building my personal brand with my username @tomlulofs. Or change my username to a spare account i've got which is called @dutchentrepreneur? Thanks for your time.

I hate to say this but... Bump.

Keep your name. Nothing more recognizable then that. AS to those fancy names "cutedutch", "dutchenterprenour", etc., no one will recognize you as much as your own name.
Nike and Adidas are not known as "thegreatsneakermakers", and Coca Cola/Pepsi don't go around with "Thecolayouliketodrink", etc.

Don't reinvent the wheel.

Your name is unique as it is.

Yes, I recommend that you grow the account with your name, so that you can grow your personal brand.
