Eyeing two laptops. One has an i5-10300 with 256 SSD, the other i7-10750 with 512 SSD. I care about asthetics, i7 is ugly. Which do I choose?

I'm assuming you're referring to the Omen laptops. The i7 has a better cooling system but an odd design. I prefer the i7 over the i5 however I'd prefer a better designed screen. Why not go for a Predator instead? The Helios 300 or 500 are roughly the same cost but better in design and I trust Acer more than HP. Alienware is also a good choice and is made by Dell but I've had a few bad experiences with Dell so I'm not keen on that one.

So you don't want the faster one because it's ugly? Looks like you've already made a decision.

With no clue what prices, what job or software the one you choose would do, a suggestion is flip a coin.

just pick whichever one you want
