People like to look down on the Patriot when they don't own one and they have never even driven one. Yes the Patriot comes with either a 2.4 or 2.0L inline 4.
You should make a day of going to your dealership and test driving both vehicles. The one thing that I can say is that the Grand Cherokee will hold its value better than the Patriot. It does seem like you keep your vehicles for a while so that may not bother you. If you test drive a Patriot make sure you see how you like the CVT.. If you have never had one like I haven't. It does take some getting used to. The Patriot is more capable than it gets credit.
