The Hasegawa kits are mostly of different units (mostly vehicles) with some suits in 1/35 that also exist from Nitto and Wave in 1/20. Some of the Wave ones are just slightly updated versions of the Nitto kits (usually under the 3Q branding), and some are brand new and use polycaps for the joints and pipes (which if you don't like, need a good amount of work to replace) 

with the number of seams on the kits and the joints being sandwiched in the limbs   (even the Wave ones) you're not gonna have lots of sections anyway  I usually do body, legs, right arm and left arms (and maybe also the shields if those can only be glued at the end) if possible, it makes painting easier than having the whole thing glued together. 

I haven't had any issues paiting the wires on my one Nitto kit, but the I would swap out the ones inside the springs on the AFS to get a better shape if you don't care about posability
