@Hazydays whether it's better or worse is a subjective thing but certainly I agree with you there's a big difference between hand pumped cask ale and kegged or bottled versions.
I think the risk of having little or no carbonation is you're leaving the beer exposed to oxygen so it'll quickly oxidise/go stale - feel free to search to forum for discussions on the wisdom of CAMRAs policy around this point!
I think a lot of homebrewing advice is skewed by the dominance of American content, a nation that seems to prefer their beer colder and more carbonated.
So when I was bottling beers I found myself gradually reducing the amount of priming sugar to get the level of carbonation I like in my beers - for me the actual number of volumes of CO2 is irrelevant, it's about what you like.
Now I've switched to kegs I'm doing similar:
I've raised the temperature of my kegerator from 6 to 8degC - important because CO2 dissolves more readily at lower temperatures (=> more fizzy)...
...and also backed off my regulator from 15 to 10-12psi - again, it's just a number on a dial, I prefer to go with my taste buds.
I felt 6degC was fine for American IPAs but too cold too properly taste my Bitters, Porters & Stouts. Of course it'll warm up eventually but I'm happier serving at 8degC (for the bitter I currently have on I could still go a tad warmer, but it's a good compromise for different styles).
And having dropped the pressure a bit the level of carbonation is closer to a traditional hand pumped cask beer - it's still a bit higher than that I think, but nowhere near the level of carbonation of bottled bitters you can buy in the supermarket.
Final point I'll say is I consider myself lucky to have reached a point in my brewing where I can worry about these little details. Having said that, I have a feeling that packaging and dispense, however you do it, is an important but much overlooked aspect of the hobby.
