I do laugh at people who can consider the current Chimera to be 'omg it is thu best escortz' as it simply isn't. RA Patrol escort is more effective, minus the console abilities. And theres plenty of 9 console store ships which are also superior.
Its stats are shoddy, it loses a console slot for the Tactical mode, Boff slots are questionable... I use mine as a phaser beam boat as thats the only fun way to play the damn thing. Most of the time it stays in the shipyard and I rock out with the Fleet 'Defiant' or Blockade Escort as they are both just so much better
A Ship inferior in everyway is somehow superior? Logic isn't quite your strong suit, it would appear.
The Chimera far ecplises any of the Ships you mentionned, but hey, you can't even be trusted to read their stats, so I wouldn't expect good analysis from you.
