Looking for a different site than ModThSims

Hosting your files and getting your content where people will see it are two different things.

You can choose a site that does both, like MTS or TSR, but you can also host them just about anywhere and then promote them through a variety of methods -- a studio here, submitting them to a content aggregation site/blog/Tumblr, posting links in 'promote your new stuff here' sections of forums (especially those focused on the type of content you're making), etc. (You can even put them on a site like MTS and then also promote them elsewhere.)

I appreciate the fact that MTS has standards for the quality of screenshots and info creators have to provide, and I wouldn't bother browsing a site that let people upload so easily if it didn't -- it'd be full of badly made content and badly presented content, and the only way to tell the difference would be to download it and test it. But their standards aren't the only acceptable way to present CC -- nor do they claim to be -- and I don't often feel like meeting them myself, and people post CC in all sorts of places.

If there is something you especially want to be seen, one of the best ways is submitting it to a big content aggregator like Sims4Updates or MaxisMatchCCWorld (to give an example of two very different types), or a topic-specific one.

You could also recruit someone who's better at words to write your text in exchange for giving them credit, fulfilling a request for them, etc. (The WCIF/Request/Collab section here is a good place for something like that. I wouldn't offer to do it for a stranger when I don't know anything about the CC, but if I saw a request for help that included some info, like a brief description and a screenshot, I might respond if I had time.)

I agree with Leniad open a studio and post here. I have always felt that Sims 4 Studio is a stress free place to share creations. I have been asked several times to move to another site (including MTS) or to just upload somewhere else and with one exception I have always politely refused. I don't create to become well known or have thousands of downloads I just make things I want for my game and then enjoy sharing them. Here is the perfect place for that.
