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!
