LG v20 vs iPhone X and iPhone 8?

I'm tempted to get a lg v20 mainly because I can expand memory and I trust their wireless charging. Also they don't cost as much currently and they are easy to fix let alone replacing the battery is extremely easy. But parts wise and performance wise since I'm not too familiar how do they compare to the iphone new generation. I would get the lg v30 but it just came out and is too much. My current phone is an iphone 5s. Also how long would a v20 generally last?

Well the 8 & X also use the same wireless charging standard so there's no difference there.

Yea, the battery is removable for the V20, but not much people, if any, actually carry around spare batteries.

Most Android phones (apparently) get about 2 years worth of upgrades (on a fragmented system). As far as it lasting, that's up to your maintenance.

That iPhone you have is on its 5th year of updates & will continue to get them until about mid-September 2018 (6 years). So assumedly the 8 & X would also get about the same amount of time for their software updates.
