Close city spacing is the absolute best strategy though.
Define "close". A city without food within reasonable borders is going to stagnate for a long time. The bombard damage is a pretty high price to pay for 3

Close city spacing is the absolute best strategy though.
The best distance is still absolute minimum. There are simply more benefits of 2 small cities than one big city. The only occasion where tight packed small cities is not best is culture victories. This is not to say this is the only strategy, but at present, no other method has produced faster victories or better scores. If you are a player that does not micromanage or doesn't like min max gaming, larger spacing would probably suit you better. Otherwise ics is still the best from settler to deity.
And all I get in return is more great scientists, faster research, and easier wins
So what, a city every 3 hexes? That's +2, and half production per city. And the benefit? Bombard damage and an extra 5-yield base tile.
How many clear tiles between two cities if you want the citys to grow to the biggest size
How do you get more scientists exactly? By running 1 in each university that takes 25 turns to build?
not faster scientists, but defn the raw pop growth from 1 to 4 is enough to power through tech.
Oh yeah, these 5-10 beakers will save my tech race. I'll rather trade away my non-surplus happiness luxury for an extra RA.
The power in ICS isn't having 2-3 extra cities, it's having 10-12, and bringing them to maturity in relatively short order. So you're not talking about 5-10 extra beakers, you're talking about 50-60 - before the Libraries, Universities, and Public Schools are considered.

What setting is that? On Deity settling peacefully to 10~12 cities on normal speed/normal map?The power in ICS isn't having 2-3 extra cities, it's having 10-12...
The only way to settle this would be to have Bibor play Sneaks 1v1 in a best of 7 series (to mitigate the effects of random terrain for both players). My money is on Sneaks...
