Skateboard buying help

It's my first time buying a skateboard. I've been wanting to buy one since 2-3years. Now's the time.

I've attached the 6skateboards with decreasing interest. which one should I get?

I like the panther dankies the most but 8.25* isn't available (which I think is my size), followed by leopard dankies.

also dankies vs hearty? is there any significant difference?

• I’ll be cruising most of the time, but I want to & will try learning some tricks too.

• My feet size is UK10. and height 5’9”. Should I get 8 or 8.25?

  • dankies—they are recommending 8.25 for my height & feet size. but I’m uncertain, should I get 8 instead or will it feel smaller for my height & feet size? making it harder to keep my feet stable on the board with little cramped space?

• My budget is 5-7k. I want something that lasts a long time & feels good quality- hence the budget. (In the hope that I'll be using it & trying to learn everything I can).

also should I get helmet lmao, Ik I'll fall hard a couple times lol.
