First of all try posting in the right forum - this is the buy/sell.

Second try searching - all those questions have likely been answered hundreds of times before.

Thirdly "what's the best" questions usually give you a bunch of different answers based on a bunch of different opinions and not necessarily what's best for you. Researching yourself and coming to your own conclusion is usually going to yield what is "best" for yourself.
