We need a few more qualifications otherwise everyone will just recommend their own favourites and you'll end up with as many recommendations are there are cycle shorts.
E.g.
Budget - how much are you wanting/willing to pay?
Use - are we talking long distance road cycling, mtb, commuting, evening ride to the pub?
Sex -

we'll assume you're male - this cuts the possibilities for recommendations by roughly half
Style - tight lycra v. baggies
Worn with other clothes i.e. undershorts, or stand alone, as it were?
etc.
