What's the better value between these 2:
$242 - Lenovo ThinkPad T480s 14" FHD i5 8th Gen 16GB RAM 512GB NVMe SSD Win 11 Pro – Refurbished Laptop

>Display: 14" Full HD (1920 x 1080) Anti-Glare Display
>Processor: Intel Core i5 (8th Gen, Quad-Core, up to 3.90GHz with Turbo Boost)
>original charger included

or

$210 Lenovo ThinkPad T480s 14" Core i7 16GB SSD 512GB Black 2018 - Used Very Good
>Processor: INTEL(R) CORE(TM) I7-8650U CPU @ 1.90GHZ

Or do I keep waiting? Is the i7 that much better than the i5 on these t480s?
