Blog subdomain or path better ?

I'm at a crossroads with a decision regarding blog integration for two of my brands and I'm hoping to gather some insights from this knowledgeable community.

Background:
Both of my brands have their main websites built using React. I'm now looking to add a blog to each site, but I'm uncertain about the best approach to take. Here's where I need your advice:

New Domain vs Subdomain: Given that these brands are relatively new, would it be more beneficial to build the blog on a completely new domain or should I consider setting it up as a subdomain? I'm weighing the potential SEO impacts and brand cohesion aspects of each option.

Subdomain with Redirect: Another consideration is setting up the blog on a subdomain (e.g., blog.branddomain.com) and then implementing a 301 redirect from the main domain (domain.com/blog). What are the pros and cons of this approach, particularly in terms of SEO performance and user experience?

My main objectives are to enhance the overall visibility and SEO strength of my brands while providing a seamless user experience.

I would greatly appreciate any insights, experiences, or recommendations you might have regarding this situation. Has anyone here faced a similar dilemma? What worked best for you and why?

Thank you in advance for your time and advice!

Just setup it on subfolder like
yourdomain.com/blog

this is the best practise, just make sure to make it look like main site to give good user experience ...

personally i like subdomains more, but its easier to add a subdirectory as you will instantly get the juice from the main domain, as it is clear to the SE's that its part of your site.
a subdomain will by default be treated as a own property, so you also have to link it properly from the main domain and include it in the main domains sitemap etc. if you want the SE's to see that its part of your main domain and not just a new site. there are a lot of things to consider, so a subdirectory is usually the easiest option.

Using github and vercel to host, so kinda don't know how i can create a subfolder that way

In my point of view path is better than the subdomain

A subdomain is generally better as it can be more easily customized and is more distinct from the main domain.
