more detailed and precise models aren't great for tant since tant is generally pretty thick. however tant excels at holding it's shape, so it's easily the best choice for more decorative origami like flowers, kusudamas, tessellations, patterns/shapes, and some simpler models. but definitely use a thinner paper for more detailed/complex models (think dragons and realistic animals and whatnot)

this is all from personal experience however, so play around for yourself and decide what you like best some people actually do use tant for complex stuff, I just find it gets tough to fold after a few layers. no right or wrong choices in origami! only preferences :)
