A face only a mother could love.
I tend to operate on the "pick 10+ cool models" whilst following some self-imposed guidelines:
2-3 "assault troops" with rifles, close range or template weapons
2 long range models (usually a HMG and sniper) to support assault/countersnipe
1-2 Thermal Optic Camo or AD troops to "deepstrike" (too many = not enough orders)
1 expensive model with an awesome combination of powers or equipment
1 anti-heavy (bazooka, missile, EM mauler, another hacker etc)
1 medic (engineer if mechs)
That's a rule of thumb and I figure it will allow me to deal with most threats. I haven't gone sectorial armies but I just ordered some Shavasti; simply as they feel more "alien" than the Morat and I like the sculpts.
I thought the SHAVASTI Starter Box had decent options:
Seed Soldiers x 3 (incl 1 lgl)
I then added:
I'll be interested to see how the plasma rifle works in practice
I'll probably add a Mechanoid medic and 3 Gwailos (bs, mr, sp) so I can change up from the Seed soldiers for more direct tactics. I'm not sure what to do for a hacker - perhaps another Noctifier or Shrouded. I'm thinking the latter as I already have 2 "TO" troops.
I'm dubious about the Skiavros and Charonid (I can't see myself deploying them both at once) but they go in under the "rule of cool." I did think the fast Vector Operators sound interesting (mimetism+superjump) but they have ugly sculpts - the HMG on one looks like a drainpipe and the hacker is simply 'meh' overall.
My order went away today, but if you have suggestions for my follow-up order, please let me know.
