Not sure which laptop to buy and how to choose?

I am looking for a laptop around $750 with a decent processor and graphics card. I am currently looking at the New Dell G3 15 Gaming Laptop, the Dell G7 15( https://www.dell.com/en-us/shop/cty/pdp/spd/g-series-15-7500-laptop/gn7500ehzth ) Gaming Laptop (with a 9th gen intel core), the Inspiron 15 5000 Laptop, and the New Inspiron 14 5000. Just to clarify, I want to buy the cheapest laptop possible that is able to play light gaming smoothly. I am not a huge gamer, but want an ok graphics card just so that I can run a few simple ones (e.g. Minecraft, Rocket League, etc...). Which of these should I buy, or is there a cheaper ( https://www.fineedus.com/ )/ better alternative( https://www.aidinggo.com/ )? Thanks.
