Curious as to your choice of these two keyboards to look at. Both of them are arrangers, which means they're really designed to play accompaniments for you while you play the melody. They've also got built in speakers, which, while convenient, also tend to be lacking in frequency response and volume.
This is not to say that these are killer features, just that it's interesting that you picked two arrangers to look at while not mentioning in your post anything that makes them arrangers. I'm wondering if you'd be happier with a non-arranger keyboard.
Another issue with both keyboards is that they're only 61 note keyboards, rather than the 88 of the standard piano keyboard. What type of piano music are you interested in playing? If you are playing only through the early romantic era, then the keyboard will be fine. But if you're going past the mid 1800s, composers starting using the range provided by modern pianos.
Lastly, both are unweighted keyboards, rather than a weighted, piano style keyboard. There is nothing wrong with an un-weighted keyboard, but if you're planning on playing a "real" piano at some time you may have a bit of a surprise. (I've got two keyboards in my electronic stack. One an 88 note weighted one, while the other is a 76 note unweighted one. They both serve a purpose. I just don't know what your purpose for this keyboard is.)
