I don't wish to risk derailing this thread by talking about the technology of a different licenced universe - not least since
there's already a thread for that. Nor do I wish to go too far off-topic by referring to how many of the designs from said universe have been turned into miniatures - not least since
there's already a topic for that.
Even so, with some of the discussions which have taken place in this thread thus far, I thought it worth comparing and contrasting them to how things are set up over in the Star Fleet Universe, if only briefly.
As a disclaimer: I don't claim to speak for anyone at ADB, though I have had a number of articles published by them.

The way
the "standard" Alpha Octant timeline tells it, the era of the Federation
Constitution-class heavy cruiser and of the Klingon D7 battlecruiser is the fourth generation of faster-than-light technology - or what the
GURPS Prime Directive role-playing game system marks as Tech Level 12.
Tech Level 9, the first to allow FTL travel, saw the onset of fusion-powered "Non-Tactical Warp", or "impulse" drive.
As shown here, NTW-powered ships could travel approximately nine parsecs per day at a "cruising" speed, yet still had to slow to "sub-light" speeds to enter combat. This is the era in which the first Romulan War was fought.
Tech Level 10 saw the onset of the first "Tactical Warp" drive: powered by matter-antimatter reactions, regulated by those all-important dilihium crystals. This allows for the first combat at (low) warp speeds. In Federation space, this "W-era" saw ships from the various "planetary" fleets receive Tactical Warp refits to their NTW starship designs, as well as the first political efforts to establish a unified Star Fleet.
Tech Level 11 was the first generation designed from the keel up to incorporate Tactical Warp drive. The engines on these "Y-era" ships were more powerful than those of the preceding era. This was the era in which the first "saucer-and-nacelle" designs were constructed for use by a unified Star Fleet; not even the Terrans had fielded such designs prior to this (there is no
NX-01 in the SFU). So this was seen an an important step away from the old planetary designs towards a shared and standardized template. Well, except for a rugged old Terran ship class which was more cost-effective to upgrade than to replace with a new light cruiser design...
Tech Level 12 is where one sees the fabled
Constitution-class; its "Franz Joseph" stablemates from the
Star Fleet Technical Manual (such as the
Saladin-class destroyer and the
Federation-class dreadnought), plus a number of "SFU-native" designs like the
Burke-class frigate. Critically, the Romulans were still mostly stuck at Tech Level 9 for much of this era; their power would remain simple impulse until a landmark treaty with the Klingon Empire saw them jump up to TL 12.

According to the SFU timeline, the famed "five-year mission" dramatized for tri-video took place between Y154 and Y159, while the prior incident at Talos IV took place in Y142.
Star Fleet still had many of the old Terran light cruisers in service; in the TL 12 era, these were referred to as the
Texas-class. Meanwhile, the Federation Police (think of them as a "Coast Guard" in space) had their own police ships which had branched off from a design lineage established by the old warp-refitted Terran destroyer. While various Federation member planets (such as Earth, Vulcan, Andor, etc.) had their own National Guards, these typically comprised of hand-me-down ships which had served in Star Fleet in the TL 11 era.
As for the Klingons, they had a variety of hull types which served alongside the D7 battlecruiser: the D6 heavy cruiser (technically superseded by the D7, though one fleet yard continued to build them nonetheless), the F5 frigate, the E4 escort, and the C6 dreadnought. When the Treaty of Smarba was signed with the Romulan Star Empire, a number of old D6s would be sold to the Romulans and converted into KRs.
The Romulans would install warp upgrades to their "Eagle-series" ships (turning the sub-light Warbird into the warp-powered War Eagle, for example) and convert a series of Klingon-built "Kestrel-series" designs. Over time, as they became more acquainted with Klingon technology, they would design their own "Hawk-series" ships - such as the SparrowHawk light cruiser - from the keel up. But then, the Hawks don't show up until after the events of the "five-year mission", so lie somewhat outside of the scope of this comparative study...

Again, I don't wish to derail any of the discussions or design choices being held in this thread. So if none of the above is deemed to be a relevant point of comparison, fair enough.
Also, I'll note in passing that most Federation miniatures listed on ADB's Shapeways storefront - to include the old Terran light cruiser - are presented in both "standard" (with panel lines on the hull) and "classic" (no panel lines) iterations.
