I am deciding between 2 of the Dell XPS 13. A few of the specs of both are below. Which has better and more stable hardware? Midknyte's cpu link on comparing them was a bit confusing to me and which has the better benchmark. Both have 128GB SSD's. I would assume 128GB is large enough for win 10 with room for some storage?

7th Generation Intel® Core™ i3-7100U (3MB Cache, up to 2.4 GHz) vs. 7th Generation Intel® Core™ i5-7200U (3MB Cache, up to 3.1 GHz)


4GB LPDDR3 1866MHz vs. 8GB LPDDR3 1866MHz

13.3 inch FHD AG (1920 x 1080) InfinityEdge display vs. 13.3 inch FHD AG (1920 x 1080) InfinityEdge display

Both have Intel® HD Graphics

Both have Killer 1535 802.11ac 2x2 WiFi and Bluetooth 4.1


Both come with Microsoft Office 30 Day Trial and McAfee LiveSafe 12 Month Subscription. I would prefer that it didn't come with any software.
