The stats are arbitrary numbers used to represent the capabilities and resilience of the fighter and how they match up against other ships.
The stats are, or SHOULD, be derived from the ship. The ship should not be built from the stats.
The 'stronger' ships are the exact same ships, just brought up to the level of the other 'top tier' VHFs from vanilla.
Take a look at vanilla's 'tier' system, designed to give the illusion of progress and increased difficulty through bigger numbers instead of different tactics or the like. You ran into Valkyries in Liberty during the campaign that were a match for the local Liberty Defenders because that was what you were expected to be flying at the time, even though the Valkyries you later encounter in Rheinland were significantly 'stronger', or rather, they had larger numbers.
