Some comments:

• It has some unique content you will not find in both of them, if you are the kind that looks for specific releases.
• The black Friday deal is usually really worth it.
• There is no in-site forum, but instead a discord channel. Their "forum" link sends you to their discord.
• The free account is deleted "after 14 days of inactivity" but it can happen earlier than this.
• Paid activation happen manually, so, if discord receipt is a privacy nightmare for you, hope they read the e-mail.
• Performance is ages ahead of dog.
• Unlike dog, they accept requests for content (via discord) and they really go after it for you, that is really nice.

Overall, it is a mix of both you mentioned, but you will find content there that you will not find on dog and vice-versa. I believe they cover geek well enough. Note that it all depends on what content you are after,
