All those brands have a decent to great reputation. What you need to ask yourself is the material (glass or ceramic) for the DT. Glass is heavier but easier to clean and won't scratch. While ceramic is lighter but can scratch. Since you are looking at a smaller tank then weight shouldn't be much of a factor.
The only other factor to determine is lights. What I understand all of the stock lighting in these tanks will only support softies.
Good luck,
