>>11026203The only correct answer is always to just get whichever has a design you like. Look up FAG, Megami Device, Dark Advent, 30MS, Nuke Matrix, ATK Girl, and Sousei Shojou etc. and just pick a couple you like the most. They are all made for teenagers to build but can be refined more when you have more ability. Almost none of them even require a bare minimum of real modeling skill, they are snap fit/push fit. Bigger, more complex ones aren’t harder, they just have more parts and take longer.
There is never even the slightest reason not to grab whichever ones appeal to you. But my personal favorites offhand are Dark Advent Rania because I just love her design that much, MS General’s Ox oneesan, and maybe uhhhhh…Luluce from 30MS. Not because they’re special as model kits but because I just like their designs and personas and expressions.
I would recommend something that has a lot of color separation in its parts so you don’t have to use a lot of stickers or paint and can have something great right off the bat, though. So not Plamax or Arcanadea, they are missing a lot of colors. But again, if you really love those, just get them.
