I see some ways to make them desirable in other areas but that would be way off topic.
Based on the original statement, it's not off-topic. A larger ship, i.e. one with more jump range, would be better in terms of jump travel
. That's why it makes for an easier start, for those who want to jump around right away.
However, it may well NOT be better in other areas, such as sub-FTL speed and manoeuverabilty. If they both have the same engine, then the smaller ship will be a better performer at sub-FTL assuming Newton's 2nd Law. I'm already presuming that the pseudo-physics is ignoring Newton's 1st Law like most space games i.e. we can fly around like aircraft in space. Apart from the excellent Orbiter
simulator, I don't know of anything that is fully Newtonian.
So in general, larger ships will be more sluggish (sub-FTL) than smaller ones if they use the same technology. I suggested a larger, more jump-capable one, purely to allow an easier start for those who may want it. I think that's a perfectly legitimate thing to do, and doesn't imply any general rule that larger ships are always better
than smaller ones. If you want to argue that a large start ship should also have better technology engines so it's just as manoeuvrable, making it even easier, by all means do so!
So really, this is a specific quantitative (range) argument, not a general qualitative (better/worse) one.
