I moved to 25s when I picked up my brand new race bike a year ago - Schwalbe 1's . I was initially sceptical having ridden through the 90s on 19mm Continental Tubular race tyres (Triathlon and road racing) and on 22s or 23's since the 2000's (road racing).
But 25s do everything people say, ride slightly lower pressure, better ride, more grip. The biggest difference is descending where the extra grip and added confidence is most noticeable, seems like you have an added margin for error and don't feel on the limit. A friend of mine runs 25 Contis and showed me he was wearing out the sidewall logo as he had the confidence to lean further into corners!
