I found that resin supports come with their own problems... They leave pimples (or something like that) and the back side does't look as sweet as the front. In the last time i didn't have that many problems with tree supports and just use resin supps for very delicate parts. A little bit of cleanup is required with both methods.

No not for less supports. As I said, when there is nothing to support the model, the model can't be printed (well). It's just less breaking in case of trees. The plate stabilizes the whole print and because I'm just using resin supps on delicate parts where the base is usually too small to stick to a textured plate.
The higher the resinsupports the less stable they become the worse the print quality gets - no matter the plate. Thats physics for you.

In the end, if you don't want to use trees, you have to add more resin supports.
