I.e. heres an analogy
We discovered and made "bread" before we made cake.
But im not going to say "compared to the cake we havent discovered yet this bread is dull and unappealing"
The bread came first so its the benchmark.
Same way im thinking here.
First came the ISD.
Then came the SSD, which was a huge difference in both size and weapondry so it made sense.
Then came the RSD, which is smaller than the SSD by 16km, yet it has nearly 1/3rd the amount of guns?
Yeah, no.
Does the RSD look good? For me yes. Does its weapondry make sense? Hella no.
