All three boots are soft flexing and high-volume, and would best suit a conservative intermediate skier. I don't have experience with these exact boots, although I've skied in boots from all three brands. In order to give a recommendation, I need to know your relative foot size (wide/narrow, low/high instep, etc.) and your skiing ability. If you are beginning to learn how to carve, these boots could work for you, but they are not a good choice for an advanced skier.
Also, the Modo series seems a little "gimmicky" to me, with the ski/walk and "extreme comfort"- essentially, lack of accuracy and performance. In the tecnica lineup, I would look more at the Vento 8 or 10 and low end Diablo series for an intermediate skier.
