I would tend to agree with the above, although it just goes to show how different people like different things. For IMC the PA28 probably is best (although that isn't what the original poster asked). Another reason I don't really like the C152 is the silly throttle control which (I know a lot planes are like this) is not logical (whoever heard of closing something by opening it?) and rather like the wing position is not like 'real' aircraft. The Warrior with everything from its direct nosewheel steering to its rudder trim just makes one think that Piper was trying to design a plane of much higher calibre than the C152.
One little point for the Liberty though, in the US, 'Liberty Nxxxx' makes a very cool callsign. 'Warrior Nxxxx' is pretty cool also, but Cessna Nxxxx is just rubbish...
