I gave both a quick look but they seem to function in essentially the same way. My first blush impression is to go for the cheaper one. My only concern in that regard might be ink quality (richness of color) but that's impossible to know without direct comparison of the two.

All that I can say with certainty is that I am currently using the MacroEnter version of the CIS system and it works beautifully so far. The feed works like a charm and color clarity is really good. The only problem I had was placing the reserve tanks on an uneven surface which caused some of the ink to leak all over my counter . My stupidity aside, the system seems to do its job as advertised and at frankly an amazing price for that much ink.
