Uk CS PhD: spend one year figuring out what you are doing, 1/1.5 years doing research. 1 year writing up. Thats the summary I've gotten from several faculty.
On top of that, you have to go do a few postdocs if you want to do academia.(maybe a good thing, but not necessary in hot areas in the US for PhDs from highly ranked schools)
There's a reason the UK is trying to go over to centers for doctoral training and 5 year PhDs. Yes, in those and the US system, you spend 2 years taking classes. But in that time you are also getting spun up and then doing research.
