My take on Oxford vs Cambridge.
My Justification: I am at uni at Oxford Uni(biased) but I've lived in central Cambridge for around 10 years. I have many friends at Uni in Cambridge.
Aesthetic Considerations : Cambridge has alot of nice open area's in the centre. So the main city is situated around Parkers Piece, a nice large open area. There is also Christs Peace, Midsummer Common and Jesus Green, which are both nice for relaxing and drinking on. Oxford only has Christ Church Meadows, which is pleasent. The Colleges in both cities are nearly all very nice. The river in Cambridge is more central, which is nice. Oxford has some nice individual buildings such as the radcliffe camarra.
Cambridge wins on Aesthetics by a narrow margin for its area's of greenery.
Cambridge 1 - 0 Oxford
Pubs : Both cities have a slew of tiny, old man pubs which serve brilliant ales from all round the country (The Hobgoblin [Now St Aldates Tavern] has had every guest ale in the country). Oxford probably has some more famous pubs such as The Mitre. Generally though, students don't pub as much in Oxford, they go to vlubs much earlier, whereas in Cambridge people go to pubs much later after pubbing. Cambridge has one downer, in the form of the cheap and hideous wetherspoons monstrousity called "The Regal" in the centre.
Overall this is a draw, both have nice pubs.
Clubs : Cambridge has very few and all are very small. Coco's is ok, but generally plays the same R'nB every night. Balleri's is an "uptown", expensive club and frankly not decent. Life is over 21. The Fez has great student nights on Monday night, this is probably the only student club night in Cambridge! PoNaNa's has gone downhill since it lost fatpoppadaddys as promoters. The Junction sometimes have some ok clubnights and also good live bands. Drinks in most clubs are £2-4, so quite expensive.
Oxford has many clubs, they are also generally about 4 or 5 times the size of Cambridge clubs. The Studio Lounge [AKA Filth] has fantastic cheesy student nights most nights, including Filthy Friday. Cambridge's only decent promoters fatpoppadaddys who do monday night Fez are also coming to The Studio on wednesdays which will be awesome. Park End is huge, playing a variety of music including its wednesday stuednt night. The Bridge drags students for tuesdays and thursdays for its student nights, thats huge and quite nice. Other clubs include Greens, Maxwells, Purple Turtle, The Zodiac and many others.
Oxford wins hands down on the clubs front. Drinks are around £1-3 in Oxford, so much cheaper.
Cambridge 1 - 1 Oxford
Shopping : Cambridge and Oxford have very similar shops. The only differences i can think of is that Cambridge has more pawn shops and Oxford has more porn shops. Oxford also has some nice Musical Instrument shops that have competetive prices, something Cambridge sadly lacks. Cambrige has one nice feature, which is generally wider no-car streets which you can navigate.
Overall a negligible difference.
Cambridge 1 - 1 Oxford
Food : Cambridge has some nice eateries and coffee shops. Clowns is open untill midnight and pleasent (except for the scary clowns that cover the ground floor walls). Gardiniers is good for chips. There are a fair few kebab shops but they are all concentrated on Hills Road and Mill Road and almost nowhere else. There is also a huge lack for kebab vans, with just the trailer of life and trailer of death in the centre. Cambridge has Dojo's which gets you great noodles for about £6.
Oxford has G&D's which hasthe best ice cream in either cities. It also has some nice little food places in covered market. There almost no kebab shops but absolutely loads of kebab vans, one outside most colleges (so you'll get two within 30 yards sometimes). Oxford has the noodle bar which serves good noodles for £4. Pubs are also generally cheaper for food in Oxford (£3.50 all-day breakfast at the goose).
Both cities have your typical KFC/BK/McD takeaways.
Overall Oxford gets a narrow win on account fo some nicer little food places and more quait coffee shops and kebab vans.
Cambridge 1 - 2 Oxford
"Other" Aesthetic considerations : As a bloke I will tell you in general Cambridge lacks much ... how shall we say .... decent eye candy. You'll go down the highstreet and you'll be lucky if one in every 50 people is fit! In Oxford the girls are alot fitter on average. My tab friends also regretfully agree. On the other hand girls from both uni's debate on which has fitter blokes, so there is obviously some closeness there.
Overall Oxford has it.

Can't think of more things to rate, but name the category and I'll do it.
