First of all - thank you for reading and asking a question.
There are a few worthy differences:

  1. Your outgoing vote has the same power as someone who is level 30 or higher, meaning if you get 300 votes from level 1 - you would still get the same amount of 1UPs as if all those votes were from users with level 30
  2. Your income depends on your own level. Each level gives you more 1UP tokens per incoming vote meaning if you're level 1 you get 1 1UP token but if you level up to level 18 - you're getting 2.7 1UP tokens per upvote, etc.
  3. There are no bots on Uptrennd
  4. The average quality of posts is not as high as Steemit but it's getting better with more users coming to the platform
  5. The price is rising steadily it could be a good investment
  6. There are 2UP Tuesdays where for 24 hours everybody earns double.
    I'm level 18 there because I bought some 1UPs and leveled up so yesterday I was getting 5.4 1UPs per upvote which is about 0.035 $ per vote
  7. The engagement rate is higher. I'm there for three weeks and I already have more than 50 followers and all my posts have many comments (because people hope to earn more by receiving upvotes on comments)
  8. The downvote is the same as upvote - if you get downvoted, the penalty is the same as upvote (depending on your level)
  9. There is a steem community on Uptrennd you can join.

Thank you once more for asking!

Is there such a thing as voting mana? Like, how does the amount of times I vote affect me? On Twetch, voting costs money.

In the same sense, is there any effect to how many times I can comment or post, etc.?

So you need to have more to get more? How much did you have to invest to get where you got?

There is no mana but you can only upvote one person maximum of 3 times a day.
About posting:
You can publish 3 blog posts a day.
About comments - I don't think there is a limit. You can comment unlimited times but make sure those comments are thoughtful.

If you have more - you will definitely earn faster.

I converted 0.29 Ethereum ~ 64$ to 14000 1UP tokens and leveled up to level 17th instantly = 1 vote is 2.6 1UPs. Now I'm already level 18 :)

You can check the leveling up chart here

It takes only 3324 to get to level 11 and earn 2 tokens per vote. It's about 21$ right now and if you look at 1UP on Coinmarketcap - it's growing!
