Again, LLC is a great fit if you have a profitable business and want profits can be paid as tax efficiently as possible to you and your other founders. You'll never need investors, you'll be able to borrow money because of your great cash flows, etc. And once in a while one grows to the moon while staying private and never go public.

But for most startups, you can't know if you'll need to raise funding. And funding isn't just VCs. It's angels. It's friends and family. It's even crowd-funding now that you can crowdfund equity. And maybe you even get the opportunity to go public and want to be the most public market friendly cap structure.

I have a friend whose e-commerce startup just broke over $100k per month in revenue. He's an LLC, but he's starting to realize that he doesn't have enough positive cash flow to pay for the equipment needed to lower his product costs, so now he's thinking of finding investors. And he needs a simple, easy to create equity program with vesting for key employees. And since he has no plans to be profitable soon, he's moving to a C corp.

A C-Corp is $500. It's not expensive and is the most flexible foundation to build a startup business on.

I'm also biased against LLCs because a problem endemic with LLCs which isn't necessary a fault of LLCs is that it's so easy to just start and go. I see founders who never consider vesting as a requirement. Four founders start an LLC and agree to each getting 25% equity split. Then one quits after a month and the remaining three have a big liability issue if they try to squeeze the quitter out.

A C corp usually leads to a professional cap structure where founders are forced to think through these issues a little better.
