OK; I'll try this list for my next test game.
Comments:
The new Sagitariii formation looks good; I'll give it a try, with attached Rapiers and a transport Minorus. I rather like the Rapiers here, they give the option of adding to the unit count in a reasonably cheap way.
Both Gun Minorus, Transport Minorus and Infantry support looks like attractive demi-century upgrades.
AV Crusaders sounds good.
I still think all robots should be
Fearless. If that makes them more expensive, then so be it, but Fearless doesn't make them any less vulnerable to being shot at and breaking before they do anything, which seems to be their main weakness.
I think Gun Minorus Company (BTW, should they be "Ordinatus Minorus Century", in keeping with the roman-style naming?) compares rather closely to the Guard SHT.

Compare gun minori to standard SHT's. For example stormblades to Plasma Cannon majori.
Minervan Stormblades cost 500, Plasma Cannon Minori cost 475 - almost the same
SHTs have DC3, so don't break so easily.
Minori perform much worse in engagements, with lower DC and poorer saves. They are more vulnerable to deep strikes.
Minori have shields, so can absorb and regenerate shooting. They are less vulnerable to artillery.
Minori damage output is 9x 60cm MW2+, SlowFire plus 6x 30cm AP5+/AA6+
Stormblade damage output is 6x 45cm MW2+, SlowFire plus 3x 30cm AP5+ plus 6x 30cm AP4+ plus 6x 45cm AT5+
The plasma minori have an advantage at 45-60cm range, but within 45cm the advantage shift to the Stormblade.
If we compare Volcano cannon minori to Shadowswords, the Minori are 50 points more expensive, the DC3 vs Shields difference remains, and the loadout is exactly identical, except the minori get AA from their HBs.
TL;DR: SHTs and Minori are subtly different in ways that I think reflect their parent army lists rather well, but I don't think one is very much better than the other.
