Should I get the iPhone 7 Plus or the normal iPhone 8?

I currently have an iPhone 6s and I'm due for an upgrade which I'm deciding on whether to get an iPhone 7 Plus or the normal sized iPhone 8 the reason is because I can't afford the 8 Plus so I was wondering what do you think would be the better upgrade?

Help with iPhone 6s 64gb storage

I recently bought n iPhone 6s with 64gb. My phone says 62.1gb of 64gb used. When I connect the phone to iTunes in my computer, it shows that I have 54gb free. Somehow the
"storage almost full" keeps popping up on my phone. I just updated to the latest 11.0.2 version, i reset the phone to factory mode, and nothing works. Any ideas on how to fix this?

What does it mean it says in transit?

Does it mean it will come tomorrow as scheduled what does in transit it means because i'm in DIRE NEED of this package as i have possibly might be out of town Sunday to pick apples and and go on a hayride so again i'm in DIRE NEED of this package also keep in mind i have my iphone 6 S in the box it came from apple. So what does it mean that my package is in transit and its in Doraville GA 37 minutes from my HOUSE!

Added (1). the expected delivery day is 7 to 14 days and i bought this package on Monday October the 2nd and was shipped out Monday October 2nd at 9:51 pm so its been 12 days. God Forbid i wait until Monday because FedEx ca't get Their SHT together yes i understand they have billions of packages to process and deliver every day so again what does it mean now that its in transit at Doraville GA does it mean that it is going to come tomorrow if it arrives at usps TONIGHT?

Added (2). or am i screwed until Monday?
