If Honor 10, Honor 20 lite and Honor 8x same price, which will you choose?

The Honor 10. It has a rather better CPU/GPU, USB-C, faster charging and Gorilla Glass.

for that price I'd say Galaxy A60,even though it is not on the list you put up,but if you can find it at a similar price to those you pointed out,it's a no brainer - Disclaimer - I don't own an A60,a friend of mine and my cousin do own it, I've a OnePlus 7 Pro so I don't speak out with much personal experience with the A60,just after a bit of toying around when they've let me handle it I'd figured its pretty good for its price, and after I did some research I do think it's quite a bit better than the Honor 10,8x or 20 lite,if you can find it for a similar price that is.Hope I've managed to help out a lil

If it's only the lower battery, get a portable power bank. Problem solved.

personally, i would go for the 8x

Buy Xiaomi Redmi 6 64GB and spend the rest on games on Steam :D

Honor 10

Honor 10 does have the best specs out of the three and it will apparently receive android 10 upgrade as well. It doesn't have an SD card slot though which would be a deal breaker for me.

Take a look at Xiaomi Redmi Note 8 Pro, it released like 3 months ago and should be cheaper than Honor 10 while being better at some things (battery, screen size and resolution, is splashproof and has SD card slot) and its CPU is only about 4% slower than H10 which is probably irrelevant. I bought it this black friday and I'm pretty satisfied with it so far, albeit I am annoyed with some MIUI things like not being able to change lockscreen with third-party apps and notifications going away when you look at them, instead of only going away when you swipe them.
