They're all going to claim to be the best. Some are formulated so that they soak in a bit better, but are a bit more expensive.
The first thing you've got going for you is that it's a kitchen floor, which is not a high moisture area such as a shower. That alone means that sealing the grout is not the most important thing in the world.
Second, be sure to apply 2-3 coats of sealer. Not a huge deal, but every coat will help a little.
