I'm looking to buy a bike ASAP!!! I've narrowed it down to 4 bikes. Can someone tell me which one I should get. The specs are the problem. I don't know what overall combo of components is best on each bike. Can someone that knows a lot about parts and function tell me which one to get and why? Thank you in advance!!!

Also, I don't need any advice on test riding and picking the one I like. I already know this. I need facts on what components are the best overall on each bike, and most importantly WHY. Plus, I can't test ride some of them because They don't have them in stock.

Here are the bikes (also if you have another suggestion please let me know and why):
