Placidus och whole sign? 1st or 12th house?

I have a Leo stellium in asc, Venus, mars and Jupiter.

According to placidus Venus is in 11th house, mars and Jupiter in 12th.

Accordning to whole sign all of them are in 1st house.

I feel a bit of Both. I never hold any anger. When I think something is unfair I get angry and I show it. Im the one speaking my truth in the Classroom if I think the teacher is unfair. I have no problems with confronting people, my family or my boss or anything. I never have secrets. My near ones knows exactely where they have me and sometimes maybe some people would think im too truthtelling. But my family appreciate my honesty. So thats why I dont feel like a mars in Leo 12th house. I have confident and think I Will succéed with things. My brother has a lot of secrets and that suprises me, because in relationships Im an open book for sure.

Though I have a lot of energy and passion but I dont think people always notice. I think they have to get to know me well to get in contact with my truthtelling and assertive side. But still if something is unfair I Will deal with it even if i dont know the person. But I dont ”seek” conflicts. Or maybe sometimes...

I love theatre and acting. I love spotlight. But mostly when I know people well. Im not the typical ”theater-person”. Thats more hidden in me. That speaks for mars in Leo 12th house...

So, if anyone could help me to make sense of this I would appreciate it a lot!!!

My question is... wich house system should I use? Wich makes most sense with my Natal chart according to you?

Because i figure that would be important to know so i could interpret the north node in the right house.
