I find different things I favor in all the different spreadsheets. So no silver bullet best for me so far.
an excel story ...
one company in which I was hired to be responsible for their entire computer chain, software & hardware, had 25 employees/consultants, all w/various ranges of "advanced" spreadsheet experience. Initially, I supplied the education, templates and guidelines in which they should all adhere, but that didn't happen.
Although my template was designed to be standardized, the consultants took great liberty designing their "own" templates/requirements. We were so 24/7 busy, dealing with a big transition, so, the company stakeholders relented, claiming they thought each consultant idea's "productive" and were content they included correct data.
Well, without advising anyone, next weekend, alone at the office, the governance in me built & implemented a strict excel/template system in which strict guidelines were forced on everyone, even the stakeholders, designed so that every spreadsheet leaving the shop, all it's charts and specifics, would adhere to my brand of company normalization. I designed the the look, size, fonts, placements, colors, and scripts, even added a reconciliation process for accuracy; all they did was insert specific numbers.
Well, talk about a revolution, the following Monday the consultants, as a bunch, stormed into the presidents office with their forks and daggers held high, as if I had wrongly taken away some creative right of passage which discriminated against their idea's & productivity. When I arrived, the hunt was in full progress, so I ignored the meeting + stakeholders request to explain my "arrogant" actions. locking myself in my office. The company owner soon arrived and once everyone dispersed, we had a quick 2 minute discussion, and that was that!!! Within hours/days, even tho many senior consultants hated my arrogant ass (well, at least until they required my assistance) ... productivity increased by leaps & bounds.
That administrative power, among other reasons, was why I luv'd Excel.
