Harlan Teklad (18%) or Mazuri 6F

Is there a major benefit to use one of these foods over the other or are they fairly equal in terms of quality? I can get Mazuri a little cheaper, but it's not as convenient (have to order a few weeks in advance and drive a bit further), or I have a feed store near my house that always stocks Teklad.

Thanks for taking a look!

Teklad is just better quality in general and tends to produce healthier rats.

Both are excellent. Rats smell less with the 6F. But as I stated both excellent feed.
