Dragons: Few hardpoints, lots of speed. Make good "cavalry" mechs for flanking positions. Much like a medium. Arm-mounted ballistic favour quick aim.
Quickdraw: Moderate hardpoints, fast like a Dragon. Energy & missile. Jumpjets. I'd rather be in a Shadowhawk.
Catapult: Handles a 300xl very well with it's well-shaped side torsos. Large vulnerable missile-box arms. Missile variants have JJ, direct-fire variant K2 doesn't have any jets.
Jagermech: vulnerable side torsos make XL engines very high risk:reward. Capable of lots of heavy direct-fire with high-mounted ballistic slots. JM6-A variant has lots of missile hardpoints so you can get a mix of loadouts for variety.
Thunderbolt: Some have jump jets. One mixed loadouts of energy+missile+ballistic, two energy+missile. Most energy hardpoints on a Heavy chassis.
Cataphract: Some variants have jumpjets. Solid all-rounder, very popular for ballistic+PPC builds for direct fire engagements. CTF-3D is the only Heavy with ballistics + jumpjets on the same variant.
Orion: Heaviest heavy. Mixed loadouts of energy+missile+ballistic.
You can look over the
smurfy mechlab for detailed hardpoints and to play around with loadouts. All mechs of the same weight have the same max armor, even if their stock armor is different, so all the 65 tonners have the same armor while the Cataphract and Orion have more. Mechs of the same weight have the same speed with the same engine rating, while heavier mechs run slower.
It's hard to go wrong with anything 65 tons and up although most of them offer very specific loadouts which may help you to choose one over the other.
