This is really way too vague to provide a helpful answer. I'd suggest you resubmit the question and describe (in general terms) what you're trying to sell and to whom.

Tongue in cheek answer: The best sales process is one you will consistently do! :)

I wrote a 335 page book on this topic...perhaps check out Seal the Deal. I'm not sure if it will answer your question, because you haven't shared what you're selling to whom, but maybe it will help? http://www.suzipomerantz.com/suzis-books/peek-inside-the-book-seal-the-deal/

It's tough to answer without knowing more details about what you sell and to who. I've got a one page sales process template that I can send you. Let me know if you'd like a copy.

Easy!

It does not exist.

If anyone answers this question with a definite answer, I would run a mile.

my 2 cents.

The best sales process is the one that will get you up to speed the quickest so that your sales career or your company will survive. If that's means cold calls in person do it, if that means telemarketing do it. The easiest way to figure what's the best sales method to follow is who is your top competitor, then look at their top sales people and copy them and hire them if your starting a company.

Best sales process is something unique and well suited to the company’s needs. You need to create one yourself and pitch it against your rivals in the market to see if it is the best.
Good preparation is the foundation on which the rest of the sales process is built. Spend some time in your customer’s shoes too. If you do not have a knowledge base, talk to the top performers, and ask to shadow their sales calls. Your sales and marketing teams should agree on an ideal customer profile and screen potential clients based on this benchmark. To ensure a healthy sales pipeline, reps should constantly be making phone calls, sending emails, and reaching out on social media. Now you have got the attention of a potential customer. If they do, you need to decide if your company is the best fit for them. This stage enables sales professionals to create tailored solutions that increase the likelihood of closing a deal.
