Okay first off - NEVER EVER BUY AN IPAD !.
They are cheaply made junk that lack even the basic ability to ad an sd card to expand the memory.
The screens will break if you so much as look at them the wrong way. The parts are all glued in, almost impossible to mend and they are made by a company called Foxconn.
Back when foxconn were making computer motherboards, I would not have used one if it had been given to me, free.
Apple are the biggest con merchants around.
As far as powerful goes - who told you that ?
Even a low to mid range android tablet has better processors and ram than the best ipad.
Apple are con merchants. Avoid at all costs.
Samsung do make good kit, probably overpriced but - obviously - not in apples league of money grabbing thievery.
The galaxy is faster and more powerful than the ipad - that's a given.
So of those two - it's a total no brainer.
Get the android tablet - always.
I am a full time it professional, been using and fixing tablets since they were invented. So I do know what I'm talking about.
Why anyone in their right mind ever buys any apple product, ever - will always be a constant mystery to me
