I'll start by saying accounts that require a certain number of transactions are a horrible place to put any savings and, in fact, I'd stay away all together.
However, you've asked a lot of questions here and are clearly more in-tune with this topic than most. If I was young again and just starting to try to pile some money together, I would absolutely chase the highest interest rates by taking advantage of accounts like this. If you have the discipline to hit the transaction counts and maintain the minimum balance AND leave your savings funds alone, do it.
If for a single second you think you'll go out one Friday night and blow your emergency fund, put it somewhere else.
I used to keep really elaborate spreadsheets of my spending and savings with goals set and progress charts, etc. I see the argument that the transaction count is not worth the gain in interest, but you've said you're not dealing with big numbers and 5% of $5,000 is about $255 after a year. It's not a lot but it's 5x more than a "normal" no transaction hoops high-yield savings account; you get five years of interest each year. So, yes, this is an amount of money you could probably generate by frequenting starbucks less, but presumably you're already doing that. Obviously you would keep this to an upper account balance of $5,000 and put the rest in a vanilla high-yield savings; then when administering the transactions becomes too much work close the account.
